Abstract: A search for production of the supersymmetric partners of the top quark, top squarks, is presented.The search is based on proton-proton collision events containing multiple jets, no leptons, and large transverse momentum imbalance.The data were collected with the CMS detector at the CERN LHC at a center-of-mass energy of 13 TeV, and correspond to an integrated luminosity of 137 $fb^-1$.The targeted signal production scenarios are direct and gluino-mediated top squark production, including scenarios in which the top squark and neutralino masses are nearly degenerate.The search utilizes novel algorithms based on deep neural networks that identify hadronically decaying top quarks and W bosons, which are expected in many of the targeted signal models.No statistically significant excess of events is observed relative to the expectation from the standard model, andlimits on the top squark production cross section are obtained in the context of simplified supersymmetric models for various production and decay modes.Exclusion limits as high as 1310 GeV are established at the 95% confidence level on the mass of the top squark for direct top squark production models,and as high as 2260 GeV on the mass of the gluino for gluino-mediated top squark production models.These results represent a significant improvement over the results of previous searches for supersymmetry by CMS in the same final state.

Abstract: A search is presented for heavy bosons decaying to Z($\nu\bar{\nu}$)V($q\bar{q'}$), where V can be a W or a Z boson. A sample of proton-proton collision data at $\sqrt{s}=13$ TeV was collected by the CMS experiment during 2016$-$2018.The data correspond to an integrated luminosity of $137 $\text{fb}^{-1}$. The event categorization is based on the presence of high-momentum jets in the forward region to identify production through weak vector boson fusion. Additional categorization uses jet substructure techniques andthe presence of large missing transverse momentum to identify W and Z bosons decaying to quarks and neutrinos, respectively.The dominant standard model backgrounds are estimated using data taken from control regions.The results are interpreted in terms of radion, W' boson, and graviton models, under the assumption that these bosons are produced via gluon-gluon fusion, Drell--Yan, or weak vector boson fusion processes. No evidence is found for physics beyond the standard model. Upper limits are set at 95\% confidence level on various types of hypothetical new bosons. Observed (expected) exclusion limits on the masses of these bosons range from 1.2 to 4.0 (1.1 to 3.7) TeV.

Abstract:
CERN-LHC.
The ALICE collaboration at the CERN LHC reports novel measurements of jet substructure in pp collisions at $\sqrts~= 7$ TeV and central Pb--Pb collisions at $\sqrtsNN~= 2.76$~TeV. Jet substructure of track-based jets is explored via iterative declustering and grooming techniques. We present the measurement of the momentum sharing of two-prong substructure exposed via grooming, the \zg, and its dependence on the opening angle, in both pp and Pb--Pb collisions. We also present the first measurement of the distribution of the number of branches obtained in the iterative declustering of the jet, which is interpreted as the number of its hard splittings. In Pb--Pb collisions, we observe a suppression of symmetric splittings at large opening angles and an enhancement of splittings at small opening angles relative to pp collisions, with no significant modification of the number of splittings.
 The results are compared to predictions from various Monte Carlo event generators to test the role of important concepts in the evolution of the jet in the medium such as color coherence.

Abstract: The first measurement of the $CP$ structure of the Yukawa coupling between the Higgs boson and $\tau$ leptons is presented. The measurement is based on data collected in proton-proton collisions at $\sqrt{s}=13$ TeV by the CMS detector at the LHC, corresponding to an integrated luminosity of 137 $\text{fb}^{-1}$. The analysis uses the angular correlation between the decay planes of $\tau$ leptons produced in Higgs boson decays. The effective mixing angle between $CP$-even and $CP$-odd $\tau$ Yukawa couplings is found to be $-1\pm 19^{\circ}$, compared to an expected value of $0\pm 21^{\circ}$ at the 68.3% confidence level. The data disfavour the pure $CP$-odd scenario at 3.0 standard deviations. The results are compatible with predictions for the standard model Higgs boson.

Abstract: Correlations between moments of different flow coefficients are measured in Pb--Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$~TeV recorded with the ALICE detector. Multiparticle mixed harmonic cumulants are calculated using charged particles in the pseudorapidity region $|\eta|<0.8$ with the transverse momentum range $0.2 < p_{\rm T} < 5.0$ GeV/$c$. The centrality dependence of correlations between two flow coefficients as well as the correlations between three flow coefficients, both in terms of their second moments, are shown. In addition, a collection of mixed harmonic cumulants involving higher moments of $v_2$ and $v_3$ is measured for the first time, where the characteristic signature of negative, positive and negative signs of four-, six- and eight-particle cumulants are observed, respectively.

Abstract: Inclusive and differential cross sections of single top quark production in association with a Z boson are measured in proton-proton collisions at a center-of-mass energy of 13 TeV with an integrated luminosity of $138\ \mathrm{fb}^{-1}$ recorded by the CMS experiment. Events are selected based on the presence of three leptons, electrons or muons, associated with leptonic Z boson and top quark decays. The measurement yields an inclusive cross section of $87.9\text{ }_{-7.3}^{+7.5}\text{ (stat) }_{-6.0}^{+7.3}\text{ (syst) fb}$ for a dilepton invariant mass greater than 30 GeV, in agreement with standard model (SM) calculations. The ratio between the cross sections for the top quark and the top antiquark production in association with a Z boson is measured as $2.37\text{ }_{-0.42}^{+0.56}\text{ (stat) }_{-0.13}^{+0.27}\text{ (syst)}$. Differential measurements at parton and particle levels are performed for the first time. Several kinematic observables are considered to study the modeling of the process. Results are compared to theoretical predictions with different assumptions on the source of the initial-state b quark and found to be in agreement, within the uncertainties. Additionally, the spin asymmetry, which is sensitive to the top quark polarization, is determined from the differential distribution of the polarization angle at parton level to be $0.58\text{ }^{+0.15}_{-0.16} \text{ (stat) } {\pm 0.06}\text{ (syst)}$, in agreement with SM predictions using the MGvATNLO event generator at next-to-leading order.

Abstract: CERN-LHC. Search for new top quark interactions within the framework of an effective field theory using the associated production of either one or two top quarks with a Z boson in multilepton final states. The data sample corresponds to an integrated luminosity of 138 fb$^{-1}$ of proton-proton collisions at $\sqrt{s} = 13$ TeV, collected by the CMS experiment at the CERN LHC. Five dimension-six operators modifying the electroweak interactions of the top quark are considered. Distributions used for the signal extraction are parameterized in terms of Wilson coefficients (WCs) describing the interaction strengths of the operators. All five WCs are fit to the data and confidence intervals at 95% confidence level are computed.

Abstract: CERN-LHC.The cross section for Higgs boson production in pp collisions is studied using the H -> TAU + TAU - decay mode. The measurements are performed using data collected by the CMS experiment at the LHC at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 138 fb^-1 . The Higgs boson transverse momentum (pT) is reconstructed using the visible tau decay products and missing pT. The jets are defined in accordance with STXS jet definition. The differential cross section times branching fraction is measured as a function of the Higgs boson pT, jet multiplicity, and pT of the leading jet, in a fiducial phase space defined to match the experimental acceptance in terms of the lepton kinematics and event topology. Results are unfolded to particle level.

Abstract: CERN-LHC. Deuteron production in high-energy collisions is sensitive to the space-time evolution of the collision system, and is typically described by a coalescence mechanism. For the first time, we present results on jet-associated deuteron production in pp collisions at $\sqrt{s}=13$ TeV, providing an opportunity to test the established picture for deuteron production in events with a hard scattering. Using a trigger particle with high transverse-momentum~($p_{\rm T}>5$ GeV/$c$) as a proxy for the presence of a jet at mid-rapidity, we observe a measurable population of deuterons being produced around the jet proxy. The associated deuteron yield measured in a narrow angular range around the trigger particle differs by 2--3 standard deviations from the uncorrelated background. The data are described by PYTHIA model calculations featuring baryon coalescence.

Abstract: Proton-proton interactions resulting in final states with two photons are studied in a search for the signature of flavor-changing neutral current interactions of top quarks (t) and Higgs bosons (H). The analysis is based on data collected at a center-of-mass energy $\sqrt{s}=13~\mathrm{TeV}$ with the CMS detector at the LHC, corresponding to an integrated luminosity of $137~\mathrm{fb}^{-1}$. No significant excess above the background prediction is observed. Upper limits on the branching fractions ($\mathcal B$) of the t quark decaying to an H and an up (u) or charm quark (c) are derived through a binned fit to the diphoton invariant mass spectrum. The observed (expected) $95\%$ confidence level upper limits are found to be $0.019\%~(0.031\%)$ for $\mathcal B(\mathrm{t} \to \mathrm{Hu})$ and $0.073\%~(0.051\%)$ for $\mathcal B(\mathrm{t} \to \mathrm{Hc})$.

Results are presented from a search for CP violation in top quark pair production, using pp collisions at a center-of-mass energy of 13 TeV.
The data analyzed corresponds to an integrated luminosity of 35.9 inverse fb collected by the CMS experiment in final states with two charged leptons.
The search defines two observables, $\mathcal{O}_{1}$ and $\mathcal{O}_{3}$, which are Lorentz scalars constructed with the four-momenta of charged leptons and of jets originating from b quarks or of top quarks, respectively.

Abstract: A search for physics beyond the standard model (SM) in final states with an electron or muon and missing transverse momentum is presented. The analysis uses data from proton-proton collisions at a center-of-mass energy of 13 TeV, collected with the CMS detector at the LHC in 2016–2018, corresponding to an integrated luminosity of 137 fb-1. No significant deviation from the SM prediction is observed. Model independent limits are set on the production cross section and coupling strength of W' bosons decaying into lepton-plus-neutrino final states. This analysis also sets limits on the parameters of other models beyond-the-SM. A 5.7 TeV exclusion limit at 95% confidence level on the mass of a sequential SM W' boson with SM-like couplings is found, when combining electron and muon decay channels. Results on oblique electroweak parameters, in particular on the W parameter, are also presented for the first time using LHC data. These results are combined with those from the direct resonance search to set constraints on composite Higgs scenarios.

Abstract: Bose-Einstein correlations of charged hadrons are measured over a broad multiplicity range, from a few particles up to about 250 reconstructed charged hadrons in proton-proton collisions at 13 TeV. The results are based on data collected using the CMS detector at the LHC during runs with a special low-pileup configuration. Three analysis techniques with different degrees of dependence on simulations are used to remove the non-Bose-Einstein background from the correlation functions. All three methods give consistent results. The measured lengths of homogeneity are studied as functions of particle multiplicity as well as average pair transverse momentum and mass. The results are compared with data from both CMS and ATLAS at 7 TeV, as well as with theoretical predictions.

Abstract: CERN-LHC. The multiplicity dependence of the pseudorapidity density of charged particles in proton--proton (pp) collisions at centre-of-mass energies $\sqrt{s}$ = 5.02, 7 and 13 TeV measured by ALICE is reported. The analysis relies on track segments measured in the midrapidity range ($|\eta| < 1.5$). Results are presented for inelastic events having at least one charged particle produced in the pseudorapidity interval $|\eta|<1$ ($\mathrm{INEL}_{>0}$). The multiplicity dependence of the pseudorapidy density of charged particles is measured with mid and forward rapidity multiplicity estimators, the latter being less affected by autocorrelations. A detailed comparison with predictions from the PYTHIA 8 and EPOS LHC event generators is also presented. Both generators provide a good description of the data.

Abstract: The first measurements of diboson production cross sections at a center-of-mass energy of $5.02~\mathrm{TeV}$ are reported. They are based on proton-proton collision data collected with the CMS detector at the LHC, corresponding to an integrated luminosity of $302~\mathrm{pb}^{-1}$. Events with two, three, or four charged light leptons (electrons or muons) in the final state are analyzed. The $\mathrm{WW}$, $\mathrm{WZ}$, and $\mathrm{ZZ}$ total cross sections are measured as $\sigma_{\mathrm{WW}}=37.0 \text{ }^{+5.5}_{-5.2} (\text{stat}) \text{ }^{+2.7}_{-2.6} (\text{syst})~\mathrm{pb}$, $\sigma_{\mathrm{WZ}}=6.4 \text{ }^{+2.5}_{-2.1} (\text{stat}) \text{ }^{+0.5}_{-0.3} (\text{syst})~\mathrm{pb}$, and $\sigma_{\mathrm{ZZ}}=5.3 \text{ }^{+2.5}_{-2.1} (\text{stat}) \text{ }^{+0.5}_{-0.4} (\text{syst})~\mathrm{pb}$. All measurements are in good agreement with theoretical calculations at combined next-to-next-to-leading order quantum chromodynamics and next-to-leading order electroweak accuracy.

Abstract: The event-by-event correlations between three flow amplitudes are measured for the first time in Pb--Pb collisions, using higher-order Symmetric Cumulants. We find that different three-harmonic correlations develop during the collective evolution of the medium, when compared with correlations that exist in the initial state. These new results cannot be interpreted in terms of previous lower-order flow measurements, since contributions from two-harmonic correlations are explicitly removed in the new observables. Comparison with Monte Carlo simulations provides new and independent constraints for the initial conditions and system properties of nuclear matter created in heavy-ion collisions.

Abstract: A combination of measurements of the inclusive top-quark pair production cross-section performed by ATLAS and CMS in proton--proton collisions at centre-of-mass energies of 7 and 8 TeV at the LHC is presented. The cross-sections are obtained using top-quark pair decays with an opposite-charge electron-muon pair in the final state and with data corresponding to an integrated luminosity of about 5 inverse fb at 7 TeV and about 20 inverse fb at 8 TeV for each experiment. The combined cross-sections are determined to be 178.5 +- 4.7 pb at 7 TeV and 243 +6.0 -5.9 pb at 8 TeV with a correlation of 0.41 for a reference top-quark mass value of 172.5 GeV. The ratio of the combined cross-sections is determined as R_8/7 = 1.363 +- 0.032. The combined measured cross-sections and their ratio agree well with theory calculations using several parton distribution function (PDF) sets. The values of the top-quark pole mass (with the strong-coupling constant fixed at 0.118) and the strong-coupling constant (with the top-quark pole mass fixed at 172.5 GeV) are extracted from the combined results by fitting a next-to-next-to leading order plus next-to-next-to leading log QCD prediction to the measurements, using the NNPDF31_nnlo_ascorr_notop PDF set, yielding mtpole = 173.4 + 1.8 - 2.0 GeV and alpha_s = 0.1170 +- 0.0021 respectively

Abstract: Double parton scattering is investigated using events with a Z boson and jets. The measurements are performed with proton-proton collision data recorded by the CMS experiment at the LHC at center-of-mass energy of 13 TeV corresponding to an integrated luminosity of 35.9 inverse femtobarns collected in year 2016. Differential cross section measurements of Z + ≥ 1 jet and Z+ ≥ 2 jet events are performed with transverse momenta of the jets above 20 GeV and pseudorapidity |eta| < 2.4. Several distributions with sensitivity to double parton scattering effects are measured, as functions of the angle and the transverse momentum imbalance between the Z boson and the jets. The measured distributions are compared with predictions from several event generators with different hadronization models and different parameter settings for multiparton interactions. It is observed that the measured distributions show a dependence on the hadronization and multiparton interaction simulation parameters and will hence be important input for future improvements of the simulations.

Abstract: An inclusive search for nonresonant signatures of beyond the standard model (SM) phenomena in events with three or more charged leptons, including hadronically decaying $\tau$ leptons, is presented. The analysis is based on a data sample corresponding to an integrated luminosity of 138 $\mathrm{fb}^{-1}$ of proton-proton collisions at $\sqrt{s}=$ 13 TeV, collected by the CMS experiment at the LHC in 2016--2018. Events are categorized based on the lepton and b-tagged jet multiplicities and various kinematic variables. Three scenarios of physics beyond the SM are probed, and signal-specific boosted decision trees are used for enhancing sensitivity. No significant deviations from the background expectations are observed. Lower limits are set at 95% confidence level on the mass of type-III seesaw heavy fermions in the range 845--1065 GeV for various decay branching fraction combinations to SM leptons. Doublet and singlet vector-like $\tau$ lepton extensions of the SM are excluded for masses below 1045 GeV and in the mass range 125--150 GeV, respectively. Scalar leptoquarks decaying exclusively to a top quark and a lepton are excluded below 1.12--1.42 TeV, depending on the lepton flavor. For the type-III seesaw as well as the vector-like doublet model, these constraints are the most stringent to date. For the vector-like singlet model, these are the first constraints from the LHC experiments. Detailed results are also presented to facilitate alternative theoretical interpretations.

Abstract: 'Measurements of the production of muons from heavy-flavour hadron decays in Pb-Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ and $2.76$ TeV using the ALICE detector at the LHC are reported. The nuclear modification factor $R_{\rm AA}$ at $\sqrt{s_{\rm NN}}=5.02$ TeV is measured at forward rapidity ($2.5 < y <4$) as a function of transverse momentum $p_{\rm T}$ in central, semi-central, and peripheral collisions over a wide $p_{\rm T}$ interval, $3 < p_{\rm T} < 20$ GeV/$c$, in which a significant contribution of muons from beauty-hadron decays is expected at high $p_{\rm T}$. With a significantly improved precision compared to the measurements at lower collision energy, the $R_{\rm AA}$ shows an increase of the suppression of the yields of muons from heavy-flavour hadron decays with increasing centrality. A suppression by a factor of about three is observed in the $10\%$ most central collisions. The $R_{\rm AA}$ at $\sqrt{s_{\rm NN}}=5.02$ TeV is similar to that reported at $\sqrt{s_{\rm NN}}=2.76$ TeV in a broader $p_{\rm T}$ interval and with an improved accuracy with respect to previously published measurements. The precise $R_{\rm AA}$ results have the potential to distinguish between model predictions implementing different mechanisms of parton energy loss in the high-density medium formed in heavy-ion collisions. The results place stringent constraints on the relative energy loss between charm and beauty quarks.'

Abstract: The production of $\phi$ mesons has been studied in pp collisions at LHC energies with the ALICE detector via the dimuon decay channel in the rapidity region $2.5 < y < 4$. Measurements of the differential cross section $\mathrm{d}^2\sigma/$\mathrm{d}y $\mathrm{d} p_\mathrm{T}$ are presented as a function of the transverse momentum ($p_\mathrm{T}$) at the center-of-mass energies $\sqrt{s}=5.02$, 8 and 13 TeV and compared with the ALICE results at midrapidity. The differential cross sections at $\sqrt{s}=5.02$ and 13 TeV are also studied in several rapidity intervals as a function of $p_\mathrm{T}$, and as a function of rapidity in three $p_\mathrm{T}$ intervals. A hardening of the $p_\mathrm{T}$-differential cross section with the collision energy is observed, while, for a given energy, $p_\mathrm{T}$ spectra soften with increasing rapidity and, conversely, rapidity distributions get slightly narrower at increasing $p_\mathrm{T}$. The new results, complementing the published measurements at $\sqrt{s}=2.76$ and 7 TeV, allow one to establish the energy dependence of $\phi$ meson production and to compare the measured cross sections with phenomenological models.

Abstract: Measurements of jet substructure describing the composition of quark- and gluon-initiated jets are presented. Proton-proton (pp) collision data at sqrt(s)=13 TeV collected with the CMS detector are used, corresponding to an integrated luminosity of 35.9/fb. Generalized angularities are measured that characterize the jet substructure and distinguish quark- and gluon-initiated jets. These observables are sensitive to the distributions of transverse momenta and angular distances within a jet. The analysis is performed using a data sample of dijet events enriched in gluon-initiated jets, and, for the first time, a Z+jet event sample enriched in quark-initiated jets. The observables are measured in bins of jet transverse momentum, and as a function of the jet radius parameter. Each measurement is repeated applying a "soft drop" grooming procedure that removes soft and large angle radiation from the jet.For easier navigation, figures are named with a code with each letter/number representing in the following order: ungroomed/groomed, AK4/AK8, charged, multiplicity/pTD2/thrust/width/LHA, [central dijet/forward dijet/Z+jet, PT].

Abstract: The first observation is reported of the combined production of three massive gauge bosons (VVV with V = W, Z) in proton-proton collisions at a center-of-mass energy of 13~TeV. The analysis is based on a data sample recorded by the CMS experiment at the CERN LHC corresponding to an integrated luminosity of $137~\mathrm{fb}^{-1}$. The searches for individual WWW, WWZ, WZZ, and ZZZ production are performed in final states with three, four, five, and six leptons (electrons or muons), or with two same-sign leptons plus one or two jets. The observed (expected) significance of the combined VVV production signal is 5.7\,(5.9) standard deviations and the corresponding measured cross section relative to the standard model prediction is $1.02^{+0.26}_{-0.23}$. The significances of the individual WWW and WWZ production are 3.3 and 3.4 standard deviations, respectively. Measured production cross sections for the individual triboson processes are also reported.

Abstract: The first measurements of production cross sections of polarized same-sign $\mathrm{W}^{\pm}\mathrm{W^{\pm}}$ boson pairs in proton-proton collisions are reported. The measurements are based on a data sample collected with the CMS detector at the LHC at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of $137~\mathrm{fb}^{-1}$. Events are selected by requiring exactly two same-sign leptons, electrons or muons, moderate missing transverse momentum, and two jets with a large rapidity separation and a large dijet mass to enhance the contribution of same-sign $\mathrm{W}^{\pm}\mathrm{W^{\pm}}$ scattering events. An observed (expected) 95\% confidence level upper limit of 1.17 (0.88) fb is set on the production cross section for longitudinally polarized same-sign $\mathrm{W}^{\pm}\mathrm{W^{\pm}}$ boson pairs. The electroweak production of same-sign $\mathrm{W}^{\pm}\mathrm{W^{\pm}}$ boson pairs with at least one of the $\mathrm{W}$ bosons longitudinally polarized is measured with an observed (expected) significance of 2.3 (3.1) standard deviations.

Abstract: Measurements of the total and differential fiducial cross sections for the Z boson decaying into two neutrinos are presented at the LHC in proton-proton collisions at a center-of-mass energy of 13 TeV. The data were collected by the CMS detector in 2016 and correspond to an integrated luminosity of 35.9 fb-1. In these measurements, events are selected containing an imbalance in transverse momentum and one or more energetic jets. The fiducial differential cross section is measured as a function of the Z boson transverse momentum. The results are combined with a previous measurement of charged-lepton decays of the Z boson.

Abstract: Inclusive $\psi(2{\rm S})$ production is measured in \ppb collisions at the centre-of-mass energy per nucleon--nucleon pair $\sqrt{s_{_{\rm NN}}}=8.16$ TeV, using the ALICE detector at the CERN LHC. The production of $\psi(2{\rm S})$ is studied at forward ($2.03 < y_{\rm cms} < 3.53$) and backward ($-4.46 < y_{\rm cms} < -2.96$) centre-of-mass rapidity and for transverse momentum \pt $<$ 12 \gevc via the decay to muon pairs. In this paper, we report the integrated as well as the $y_{\rm cms}$- and $p_{\rm T}$-differential inclusive production cross sections. Nuclear effects on $\psi(2{\rm S})$ production are studied via the determination of the nuclear modification factor that shows a strong suppression at both forward and backward centre-of-mass rapidities. Comparisons with corresponding results for inclusive J$/psi$ show a similar suppression for the two states at forward rapidity (p-going direction), but a stronger suppression for $\psi(2{\rm S})$ at backward rapidity (Pb-going direction). As a function of $p_{\rm T}$, no clear dependence of the nuclear modification factor is found. The relative size of nuclear effects on $\psi(2{\rm S})$ production compared to J$/psi$ is also studied via the double ratio of production cross sections $[\sigma_{\psi({\rm 2S})}/\sigma_{{\rm J/}\psi}]_{\rm pPb}/[\sigma_{\psi({\rm 2S})}/\sigma_{{\rm J/}\psi}]_{\rm pp}$ between \ppb and \pp collisions. The results are compared with theoretical models that include various effects related to the initial and final state of the collision system and also with previous measurements at $\sqrt{s_{_{\rm NN}}}=5.02$ TeV.

Abstract: A search for new physics in events with two highly Lorentz-boosted Z bosons and large missing transverse momentum is presented. The analyzed proton-proton collision data, corresponding to an integrated luminosity of 137 fb$^{-1}$, were recorded at $\sqrt{s}=13$ TeV by the CMS experiment at the CERN LHC. The search utilizes the substructure of jets with large radius to identify quark pairs from Z boson decays. Backgrounds from standard model processes are suppressed by requirements on the jet mass and the missing transverse momentum. No significant excess in the event yield is observed beyond the number of background events expected from the standard model. For a simplified supersymmetric model in which the Z bosons arise from the decay of gluinos, an exclusion limit of 1920 GeV on the gluino mass is set at $95\%$ confidence level. This is the first search for beyond-standard-model production of pairs of boosted Z bosons plus large missing transverse momentum.

Measurement of $\rm p\overline{\Lambda}\oplus\overline{p}\Lambda$ and $\Lambda\overline{\Lambda}$ interactions with femtoscopic correlations in Pb--Pb collisions at $\sqrt{s_{\rm NN}} = 2.76$~{\normalfont TeV} and $\sqrt{s_{\rm NN}} = 5.02$~{\normalfont TeV}
LHC ALICE collaboration Baryon-antibaryon correlations in Pb-Pb collisions minimum bias trigger, -0.8 < eta < 0.8
Femtoscopic correlation functions were measured for $\rm p\overline{p}$, $\rm p\overline{\Lambda}\oplus\overline{p}\Lambda$, and $\Lambda\overline{\Lambda}$ pairs, as a function of collision centrality, in Pb--Pb collisions at $\sqrt{s_{\rm NN}}=2.76$~TeV and $\sqrt{s_{\rm NN}}=5.02$~TeV recorded by the ALICE experiment at the LHC. %They reflect the geometry of the emitting source convoluted with the characteristic final state interactions for each pair, with the strong force playing a dominant role. Correlations present in heavier baryon pairs directly influence the measurement via the so-called residual correlations mechanism. A simultaneous fit to all obtained correlation functions was performed, maximising the precision and sensitivity to the strong interaction parameters for the selected baryon pairs. Real and imaginary components of the scattering lengths, as well as the effective ranges, were extracted for combined $\rm p\overline{\Lambda}\oplus\overline{p}\Lambda$ pairs and, for the first time, for $\Lambda\overline{\Lambda}$ pairs. Effective averaged scattering parameters for heavier baryon--anti-baryon pairs, not measured directly, are also provided. The results reveal similarly strong interaction between measured baryon--anti-baryon pairs, suggesting that they annihilate in the same manner as $\rm p\overline{p}$ at the same pair relative momentum $k^{*}$. Moreover, the reported significant non-zero imaginary part and negative real part of the scattering length open up a possibility for future baryon--anti-baryon bound state searches.

Abstract: Evidence for Higgs boson decay to a pair of muons is presented. This result combines searches in four exclusive categories targeting the production of the Higgs boson via gluon fusion, via vector boson fusion, in association with a vector boson, and in association with a top quark-antiquark pair. The analysis is performed using proton-proton collision data at $\sqrt{s}=13~\mathrm{TeV}$, corresponding to an integrated luminosity of $137~\mathrm{fb}^{-1}$, recorded by the CMS experiment at the CERN LHC. An excess of events over the background expectation is observed in data with a significance of 3.0 standard deviations, where the expectation for the standard model (SM) Higgs boson with mass of 125.38 GeV is 2.5. The combination of this result with that from data recorded at $\sqrt{s} = 7$ and 8\TeV, corresponding to integrated luminosities of 5.1 and $19.7~\mathrm{fb}^{-1}$, respectively, increases both the expected and observed significances by 1\%. The measured signal strength, relative to the SM prediction, is $1.19^{+0.40}_{-0.39}(\mathrm{stat})^{+0.15}_{-0.14}(\mathrm{syst})$. This result constitutes the first evidence for the decay of the Higgs boson to second generation fermions and is the most precise measurement of the Higgs boson coupling to muons reported to date.

Abstract:
"Systematic studies of charge-dependent two- and three-particle correlations in
Pb--Pb collisions at $\sqrt{\it{s}_\mathrm{{NN}}} = $ 2.76~and 5.02~TeV used to
probe the Chiral Magnetic Effect (CME) are presented. These measurements
are performed for charged particles in the pseudorapidity ($\eta$) and transverse
momentum ($p_{\rm{T}}$) ranges $\left|\eta \right| < 0.8$ and $0.2 < p_{\mathrm{T}} < 5$~GeV/$c$.
A significant charge-dependent signal that becomes more pronounced for peripheral
collisions is reported for the CME-sensitive correlators
$\gamma_{1,1} = \langle \cos (\varphi_{\alpha} +\varphi_{\beta} - 2\Psi_{2}) \rangle$
and $\gamma_{1,-3} = \langle \cos (\varphi_{\alpha} -3\varphi_{\beta} + 2\Psi_{2}) \rangle$.
The results are used to estimate the contribution of background effects, associated
with local charge conservation coupled to anisotropic flow modulations, to measurements
of the CME. A blast-wave parametrisation that incorporates local charge conservation
tuned to reproduce the centrality dependent background effects is not able to fully describe
the measured $\gamma_{1,1}$. Finally, the charge and centrality dependence of mixed-harmonics
three-particle correlations, of the form
$\gamma_{1,2} = \langle \cos (\varphi_{\alpha} + 2 \varphi_{\beta} - 3\Psi_{3}) \rangle$,
which are insensitive to the CME signal, verify again that background contributions
dominate the measurement of $\gamma_{1,1}$."

Abstract: This paper presents isolated photon--hadron correlations usingpp and p$-$Pb data collected by the ALICE detector at the LHC. For photons with $|\eta|<0.67$ and $12 < p_\mathrm{T} < 40$ GeV/$c$, the associated yield of charged particles in the range {$|\eta|<0.80$} and $0.5 < p_\mathrm{T} < 10$ GeV/$c$ is presented. These momenta are much lower than previous measurements at the LHC. No significant difference between pp and p$-$Pb is observed, with Pythia 8.2 describing both data sets within uncertainties. This measurement constrains nuclear effects on the parton fragmentation in p$-$Pb collisions, and provides a benchmark for future studies of Pb$-$Pb collisions.

Abstract: CERN-LHC. The invariant differential cross section of inclusive $\omega(782)$ meson production at midrapidity ($|y|<0.5$) in pp collisions at  $\sqrt{s}=7$ TeV  was measured with the ALICE detector at the LHC over a transverse momentum range of $2 < p_{\text{T}} < 17 \text{GeV}/c$. The $\omega$ meson was reconstructed via its $\omega\rightarrow\pi^+\pi^-\pi^0$ decay channel. The measured $\omega$ production cross section is compared to various calculations: PYTHIA 8.2 Monash 2013 describes the data, while PYTHIA 8.2 Tune 4C overestimates the data by about 50 percent. A recent NLO calculation, which includes a model describing the fragmentation of the whole vector-meson nonet, describes the data within uncertainties below $6$ GeV/c, while it overestimates the data by up to 50 percent for higher $ p_{\text{T}}$.  The $\omega/\pi^0$ ratio is in agreement with previous measurements at lower collision energies and the PYTHIA calculations.  In addition, the measurement is compatible with transverse mass scaling within the measured $p_{\text{T}}$~range and the ratio is constant with $C^{\omega/\pi^{0}}= 0.67  \pm 0.03 \text{(stat)} \pm 0.04 \text{(sys)}$ above a transverse momentum of $2.5$ GeV/$c$.

Abstract: A search is described for the production of a pair of bottom-type vector-like quarks (VLQs), each decaying into a \PQb quark and either a Higgs or a \PZ boson. The analysis is based on data from proton-proton collisions at a 13\TeV center-of-mass energy recorded by the CMS experiment, corresponding to a total integrated luminosity of 137\fbinv. Since the predominant decay modes of the Higgs and \PZ bosons are to a pair of quarks, the analysis focuses on final states consisting of jets resulting from the six quarks produced in the events. Because the two jets produced in the decay of a highly boosted Higgs or \PZ boson might merge to form a single jet, three independent analyses are performed, categorized by the number of observed jets. No signal in excess of the expected background is observed, allowing lower limits to be set on the VLQ mass. The limits at 95\% confidence level are 1573\GeV in the case where the VLQ decays exclusively to a b quark and a Higgs boson, 1394\GeV for when it decays exclusively to a b quark and a \PZ boson, and 1449\GeV for when it decays equally in these two modes.

Abstract: The measurements of the (anti)deuterons elliptic flow ($v_2$) and the first measurements of triangular flow ($v_3$) in Pb-Pb collisions at a center-of-mass energy per nucleon-nucleon collisions $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV are presented. A mass ordering at low transverse momentum ($p_{\rm T}$) is observed when comparing these measurements with those of other identified hadrons, as expected from relativistic hydrodynamics. The measured (anti)deuterons $v_{2}$ lies between the predictions from the simple coalescence and blast-wave models, which provide a good description of the data only for more peripheral and for more central collisions, respectively. The mass number scaling, which is violated for $v_{2}$, is approximately valid for the (anti)deuterons $v_{3}$. The measured $v_{2}$ and $v_{3}$ are also compared with the predictions from a coalescence approach with phase-space distributions of nucleons generated by iEBE-VISHNU with AMPT initial conditions coupled with UrQMD, and from a dynamical model based on relativistic hydrodynamics coupled to the hadronic afterburner SMASH. The model predictions are consistent with the data within the uncertainties in mid-central collisions, while a deviation is observed in central centrality intervals.

Abstract: A search is presented for a narrow resonance decaying to a pair of oppositely charged muons using $\sqrt{s}=13$ TeV proton-proton collision data recorded at the LHC. In the 45--75 and 110--200 GeV resonance mass ranges, the search is based on conventional triggering and event reconstruction techniques. In the 11.5--45 GeV mass range, the search uses data collected with dimuon triggers with low transverse momentum thresholds, recorded at high rate by storing a reduced amount of trigger-level information. The data correspond to integrated luminosities of 137 $\mathrm{fb}^{-1}$ and 96.6 $\mathrm{fb}^{-1}$ for conventional and high-rate triggering, respectively. No significant resonant peaks are observed in the probed mass ranges. The search sets the most stringent constraints to date on a dark photon in the $\sim$30--75 and 110--200 GeV mass ranges.

Abstract:
CERN-LHC.The cross section for Higgs boson production in pp collisions is studied using the H -> W + W - decay mode, followed by leptonic decays of the W bosons to an oppositely charged electron-muon pair in the final state. The measurements are performed using data collected by the CMS experiment at the LHC at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 137 fb^-1 . The Higgs boson transverse momentum (pT) is reconstructed using the lepton pair pT and missing pT. The number of jets is defined in accortance with STXS jet definition. The differential cross section times branching fraction is measured as a function of the Higgs boson pT and number of jets in a fiducial phase space defined to match the experimental acceptance in terms of the lepton kinematics and event topology. Results are unfolded to particle level

The fiducial region is defined at particle level (using Born level leptons) as:

- emununu
- leading lepton pT > 25 GeV
- subleading lepton pT > 13 GeV
- psudorapidity of electrons and muons |eta| < 2.5
- Invariant mass of the two charged leptons mll > 12 GeV
- Charged lepton pair pT > 30 GeV
- Invariant mass of the leptonic system in the transverse plane mT(emununu) > 60 GeV
- Invariant mass of the subleading lepton and the neutrinos in the transverse plane mT_l2 > 30 GeV

Abstract: The inclusive production of the J/$\psi$ and $\psi$(2S) charmonium states is studied as a function of centrality in p--Pb collisions at a centre-of-mass energy per nucleon pair $\sqrt{s_{\rm NN}} = 8.16$ TeV at the LHC. The measurement is performed in the dimuon decay channel with the ALICE apparatus in the centre-of-mass rapidity intervals $-4.46 < y_{\rm cms} < -2.96$ (Pb-going direction) and $2.03 < y_{\rm cms} < 3.53$ (p-going direction), down to zero transverse momentum ($p_{\rm T}$). The J/$\psi$ and $\psi$(2S) production cross sections are evaluated as a function of the collision centrality, estimated through the energy deposited in the zero degree calorimeter located in the Pb-going direction. The $p_{\rm T}$-differential J/$\psi$ production cross section is measured at backward and forward rapidity for several centrality classes, together with the corresponding average $\langle p_{\rm T} \rangle$ and $\langle p^{2}_{\rm T} \rangle$ values. The nuclear effects affecting the production of both charmonium states are studied using the nuclear modification factor. In the p-going direction, a suppression of the production of both charmonium states is observed, which seems to increase from peripheral to central collisions. In the Pb-going direction, however, the centrality dependence is different for the two states ':' the nuclear modification factor of the J/$\psi$ increases from below unity in peripheral collisions to above unity in central collisions, while for the $\psi$(2S) it stays below or consistent with unity for all centralities with no significant centrality dependence. The results are compared with measurements in p--Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV and no significant dependence on the energy of the collision is observed. Finally, the results are compared with theoretical models implementing various nuclear matter effects.

Measurement of the Higgs boson production rate in association with top quarks in final states with electrons, muons, and hadronically decaying tau leptons at $\sqrt{s} =$ 13 TeV;CMS Collaboration;2021;HEPData


Abstract: A search is performed for the rare decay $\mathrm{W^{\pm}}\to\pi\gamma$ in proton-proton collisions at $\sqrt{s} = 13~\mathrm{TeV}$. Data corresponding to an integrated luminosity of $137~\mathrm{fb^{-1}}$ were collected during 2016 to 2018 with the CMS detector. This analysis exploits a novel search strategy based on W boson production in top quark pair events. An inclusive search for the $\mathrm{W^{\pm}}\to\pi\gamma$ decay is not optimal at the LHC because of the high trigger thresholds. Instead, a trigger selection is exploited in which the W boson originating from one of the top quarks is used to tag the event in a leptonic decay. The W boson emerging from the other top quark is used to search for the $\mathrm{W^{\pm}}\to\pi\gamma$ signature. Such decays are characterized by an isolated track pointing to a large energy deposit, and by an isolated photon of large transverse momentum. The presence of b quark jets reduces the background from the hadronization of light-flavor quarks and gluons. The $\mathrm{W^{\pm}}\to\pi\gamma$ decay is not observed. An upper exclusion limit is set to this branching fraction, corresponding to $1.50\times 10^{-5}$ at $95\%$ confidence level, whereas the expected upper exclusion limit is $0.85^{+0.52}_{-0.29} \times 10^{-5}$.

Abstract: The production of $\pi^{\pm}$, $\mathrm{K}^{\pm}$, $\mathrm{K_{S}^{0}}$, $\mathrm{K^{*}(892)^{0}}$, ${\rm p}$, ${\rm \overline{p}}$, $\phi(1020)$, $\Lambda$, $\overline{\Lambda}$, $\Xi^{-}$, $\overline{\Xi}^{+}$, $\Omega^{-}$, and $\overline{\Omega}^{+}$ was measured in inelastic proton--proton (pp) collisions at a center-of-mass energy of $\sqrt{s}=$ 13 TeV at midrapidity ($|y|<0.5$) as a function of transverse momentum ($p_{\mathrm{T}}$) using the ALICE detector at the CERN LHC. Furthermore, the single-particle $p_{\mathrm{T}}$ distributions of $\mathrm{K_{S}^{0}}$, $\Lambda$, and $\overline{\Lambda}$, in inelastic pp collisions at $\sqrt{s}=$ 7 TeV are reported here for the first time. The $p_{\mathrm{T}}$ distributions are studied at midrapidity within the transverse momentum range $0\leq p_{\mathrm{T}} \leq 20$ GeV/$c$, depending on the particle species. The $p_{\mathrm{T}}$ spectra, integrated yields, and particle yield ratios are discussed as a function of collision energy and compared with measurements at lower $\sqrt{s}$ and with results from various general-purpose QCD-inspired Monte Carlo models. A hardening of the spectra at high $p_{\mathrm{T}}$ with increasing collision energy is observed, which is similar for all particle species under study. The measured $p_{\mathrm{T}}$ spectra of mesons for $p_{\mathrm{T}}<2$ GeV/$c$ significantly deviate from the empirical transverse mass scaling relation based on the measured charged pion spectrum. The empirical $x_{\mathrm{T}}\equiv 2p_{\mathrm{T}}/\sqrt{s}$ scaling for $\pi^{\pm}$, $\mathrm{K}^{\pm}$, $\mathrm{K^{*0}}$ and ${\rm p}({\rm \overline{p}})$ is well satisfied in the hard scattering region of particle production. As the collision energy increases from $\sqrt{s}=$ 7 TeV to 13 TeV, the yields of non- and single-strange hadrons normalized to the pion yields remain approximately constant as a function of $\sqrt{s}$, while ratios for multi-strange hadrons indicate enhancements. The $p_{\mathrm{T}}$-differential cross sections of $\pi^{\pm}$, $\mathrm{K}^{\pm}$, and ${\rm p}({\rm \overline{p}})$ are compared with next-to-leading order perturbative QCD calculations, which are found to overestimate the cross sections for $\pi^{\pm}$ and ${\rm p}({\rm \overline{p}})$ at high $p_{\mathrm{T}}$.

Abstract: A search is presented for single production of a vector-like T quark with charge $2e/3$, in the decay channel featuring a top quark and a Z boson, with the top quark decaying hadronically and the Z boson decaying to neutrinos. The search uses data collected by the CMS experiment in proton-proton collisions at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 136 $\mathrm{fb}^{-1}$ recorded at the CERN LHC in 2016--2018. The search is sensitive to a T quark mass between 0.6 and 1.8 TeV with decay widths ranging from negligibly small up to 30$\%$ of the T quark mass. Reconstruction strategies for the top quark are based on the degree of Lorentz boosting of its final state. At 95$\%$ confidence level, the upper limit on the product of the cross section and branching fraction for a T quark of small decay width varies between 15 and 602 $\mathrm{fb}$, depending on its mass. For a T quark with decay widths between 10 and 30$\%$ of its mass, this upper limit ranges between 16 and 836 $\mathrm{fb}$. For most of the studied range, the results provide the best limits to date. This is the first search for single T quark production based on the full Run 2 data set of the LHC.

Abstract: Central exclusive and semiexclusive production of pi+pi- pairs is measured with the CMS detector in proton-proton collisions at the LHC at center-of-mass energies of 5.02 and 13 TeV. The theoretical description of these nonperturbative processes, which have not yet been measured in detail at the LHC, poses a significant challenge to models. The two pions are measured and identified in the CMS silicon tracker based on specific energy loss, whereas the absence of other particles is ensured by calorimeter information. The total and differential cross sections of exclusive and semiexclusive central pi+pi- production are measured as functions of invariant mass, transverse momentum, and rapidity of the pi+pi- system in the fiducial region defined as transverse momentum pT(pi) > 0.2 GeV and pseudorapidity |eta(pi)| < 2.4. The production cross sections for the four resonant channels f0(500), rho0(770), f0(980), and f2(1270) are extracted using a simple model. These results represent the first measurement of this process at the LHC collision energies of 5.02 and 13 TeV.

Abstract: The production of Z boson pairs in proton-proton (pp) collisions, pp →(Z/γ∗)(Z/γ∗) → 2l2l', where l, l' = e or µ, is studied at a center-of-mass energy of 13 TeV with the CMS detector at the CERN LHC. The data sample corresponds to an integrated luminosity of $137~\mathrm{fb}^{-1}$, collected during 2016–2018. The ZZ production cross section, $\sigma_{tot}$(pp → ZZ) = 17.4±0.3 (stat)±0.5 (syst)±0.4 (theo)±0.3 (lumi) pb, measured for events with two pairs of opposite-sign, same-flavor leptons produced in the mass region 60 < $m_{l^+l^−}$ < 120 GeV is consistent with standard model predictions. Differential cross sections are also measured and agree with theoretical predictions. The invariant mass distribution of the four-lepton system is used to set limits on anomalous ZZZ and ZZγ couplings.

Abstract: A search for dark matter in the form of strongly interacting massive particles (SIMPs) using the CMS detector at the LHC is presented. The SIMPs would be produced in pairs that manifest themselves as pairs of jets without tracks. The energy fraction of jets carried by charged particles is used as a key discriminator to suppress efficiently the large multijet background, and the remaining background is estimated directly from data. The search is performed using proton-proton collision data corresponding to an integrated luminosity of 16.1/fb, collected with the CMS detector in 2016. No significant excess of events is observed above the expected background. For the simplified dark matter model under consideration, SIMPs with masses up to 100 GeV are excluded and further sensitivity is explored towards higher masses. These are the first results from a search for the production of strongly interacting dark matter candidates at a collider.

Abstract: This paper describes the search for a heavy vector resonance decaying into a Z boson and the standard model Higgs boson, where the Z boson is identified through its leptonic decays to electrons, muons, or neutrinos, and the Higgs boson is identified through its hadronic decays. The search is performed in a Lorentz-boosted regime for resonances with masses larger than 800 GeV. The data samples of proton-proton collisions were collected from 2016 to 2018 at a center-of-mass energy of 13 TeV by the CMS experiment at CERN and correspond to an integrated luminosity of 137 $\text{fb}^{-1}$. Upper limits are derived on the production of a narrow heavy resonance Z' as a function of the Z' mass, and a mass below 3.5 and 3.7 TeV is excluded at 95% confidence level in models where the heavy vector boson couples exclusively to fermions and to bosons, respectively. These are the most stringent limits placed on the Heavy Vector Triplet Z' model to date. If the heavy vector boson couples exclusively to standard model bosons, upper limits on the product of the cross section and branching fraction are set between 23 and 0.3 $\text{fb}$ for a Z' mass between 0.8 and 4.6 TeV, respectively. This is the first limit set on a heavy vector boson coupling exclusively to standard model bosons in its production and decay.

Abstract: A data sample of events from proton-proton collisions with at least two jets, and two isolated same-sign or three or more charged leptons, is studied in a search for signatures of new physics phenomena. The data correspond to an integrated luminosity of 137 fb$^{-1}$ at a center-of-mass energy of 13 TeV, collected in 2016-2018 by the CMS experiment at the LHC. The search is performed using a total of 168 signal regions defined using several kinematic variables. The properties of the events are found to be consistent with the expectations from standard model processes. Exclusion limits at 95% confidence level are set on cross sections for the pair production of gluinos or squarks for various decay scenarios in the context of supersymmetric models conserving or violating R parity. The observed lower mass limits are as large as 2.1 TeV for gluinos and 0.9 TeV for top and bottom squarks. To facilitate reinterpretations, model-independent limits are provided in a set of simplified signal regions.

Abstract: This work presents new constraints on the existence and the binding energy of a possible $\mathrm{\Lambda}$-$\mathrm{\Lambda}$ bound state, the H-dibaryon, derived from $\mathrm{\Lambda}$-$\mathrm{\Lambda}$ femtoscopic measurements by the ALICE collaboration. The results are obtained from a new measurement using the femtoscopy technique in p-p collisions at $\sqrt{s}=13$ TeV and p-Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV, combined with previously published results from p-p collisions at $\sqrt{s}=7$ TeV. The $\mathrm{\Lambda}$-$\mathrm{\Lambda}$ scattering parameter space, spanned by the inverse scattering length $f_0^{-1}$ and the effective range $d_0$, is constrained by comparing the measured $\mathrm{\Lambda}$-$\mathrm{\Lambda}$ correlation function with calculations obtained within the Lednick'y model. The data are compatible with hypernuclei results and lattice computations, both predicting a shallow attractive interaction, and permit to test different theoretical approaches describing the $\mathrm{\Lambda}$-$\mathrm{\Lambda}$ interaction. The region in the $(f_0^{-1},d_0)$ plane which would accommodate a $\mathrm{\Lambda}$-$\mathrm{\Lambda}$ bound state is substantially restricted compared to previous studies. The binding energy of the possible $\mathrm{\Lambda}$-$\mathrm{\Lambda}$ bound state is estimated within an effective-range expansion approach and is found to be $B_{\Lambda\Lambda} = 3.2^{+1.6}_{-2.4}\text{(stat)}^{+1.8}_{-1.0}\text{(syst)}$ MeV.

Abstract: Measurements are presented of the triple-differential cross section for inclusive isolated-photon+jet events in pp collisions at $\sqrt{s}$ = 8 TeV as a function of photon transverse momentum (${p_{T}^{\gamma}}$), photon pseudorapidity ($|{\eta^{\gamma}}|$), and jet pseudorapidity ($\eta^{jet}$). The data correspond to an integrated luminosity of 19.7 $fb^{−1}$ that probe a broad range of the available phase space, for $|{\eta^{\gamma}}|$ < 1.44 and 1.57 < $|{\eta^{\gamma}}|$ < 2.50, |${\eta^{\textrm{jet}}}$| < 2.5, 40 < ${p_{T}^{\gamma}}$ < 1000 GeV, and jet transverse momentum, ${p_{T}^{jet}}$, > 25 GeV.

Abstract: A search for WW production from double-parton scattering processes using same-charge electron-muon and dimuon events is reported, based on proton-proton collision data collected at a center-of-mass energy of 13 TeV. The analyzed data set corresponds to an integrated luminosity of 77.4 invfb, collected using the CMS detector at the LHC in 2016 and 2017. Multivariate classifiers are used to discriminate between the signal and the dominant background processes. A maximum likelihood fit is performed to extract the signal cross section. This leads to the first evidence for double-parton scattering WW production, with a significance of 3.9 standard deviations. The measured inclusive cross section is 1.41 +/- 0.28 (stat.) +/- 0.28 (syst.) pb.

Abstract: We report measurements of anisotropic flow coefficients ($v_n$) and their cross-correlations using two- and multi-particle cumulant methods in collisions of pp at $\sqrt{s} = 13$ TeV, p--Pb at $\sqrt{s_{_{\rm NN}}} = 5.02$ TeV, Xe--Xe at $\sqrt{s_{_{\rm NN}}} = 5.44$ TeV, and Pb--Pb at $\sqrt{s_{_{\rm NN}}} = 5.02$ TeV recorded with the ALICE detector. These measurements are performed as a function of multiplicity in the mid-rapidity region $|\eta|<0.8$ for the transverse momentum range $0.2 < p_{\rm T} < 3.0$ GeV/$c$. An ordering of the coefficients $v_2 > v_3 > v_4$ is found in pp and \pPb\ collisions, similar to that seen in large collision systems, while a weak $v_2$ multiplicity dependence is observed relative to nucleus-nucleus collisions in the same multiplicity range. Using the novel subevent method, $v_{2}$ measured in pp and \pPb\ collisions with four-particle cumulants is found to be compatible with that from six-particle cumulants. We also present the symmetric cumulants $SC(m,n)$ calculated with the subevent method which evaluate the correlation strength between $v_n^2$ and $v_m^2$. The presented data, which add further support to the existence of long-range multi-particle azimuthal correlations in high multiplicity pp and \pPb\ collisions, can neither be described by PYTHIA8 nor by IP-Glasma+MUSIC+UrQMD model calculations, and hence provide new constraints on collective effects in small collision systems.

Abstract: A search for narrow and broad resonances with masses greater than 1.8 TeV decaying to a pair of jets is presented. The search uses proton-proton collision data at$\sqrt{s} = 13~\mathrm{TeV}$ collected at the LHC, corresponding to an integrated luminosity of $137~\mathrm{fb}^{-1}$. The background arising from standard model processes is predicted with the fit method used in previous publications and with a new method. The dijet invariant mass spectrum is well described by both data-driven methods, and no significant evidence for the production of new particles is observed. Model independent upper limits are reported on the production cross sections of narrow resonances, andbroad resonances with widths up to $55\%$ of the resonance mass. Limits are presented on the masses of narrow resonances from various models: string resonances, scalardiquarks, axigluons, colorons, excited quarks, color-octet scalars, W$^{\prime}$ and Z$^{\prime}$ bosons, Randall–Sundrum gravitons, and dark matter mediators. The limits on narrow resonances are improved by 200 to 800 GeV relative to those reported in previous CMS dijet resonance searches. The limits on dark matter mediators are presented as a func-tion of the resonance mass and width, and on the associated coupling strength as a function of the mediator mass. These limits exclude at $95\%$ confidence level a darkmatter mediator with a mass of 1.8 TeV and width $1\%$ of its mass or higher, up to one with a mass of 4.8 TeV and a width $45\%$ of its mass or higher.

Abstract: A search for a narrow resonance with a mass between 350 and 700 GeV, and decaying into a pair of jets, is performed using proton-proton collision events containing at least three jets. The data sample corresponds to an integrated luminosity of $18.3 ~\mathrm{fb}^{-1}$ recorded at $\sqrt{s}=13~\mathrm{TeV}$ with the CMS detector. Data are collected with a technique known as "data scouting", in which the events are reconstructed, selected, and recorded at a high rate in a compact form by the high-level trigger. The three-jet final state provides sensitivity to lower resonance masses than in previous searches using the data scouting technique. The spectrum of the dijet invariant mass, calculated from the two jets with the largest transverse momenta in the event, is used to search for a resonance. No significant excess over a smoothly falling background is found. Limits at 95% confidence level are set on the production cross section of a narrow dijet resonance. The corresponding upper limits on the coupling of a narrow vector resonance interacting only with quarks are between 0.10 and 0.15, depending on the resonance mass.These results represent the most stringent upper limits in the mass range between 350 and 450 GeV obtained with a search that is sensitive to the decay of the resonance into light-flavor quarks.

Comparison of measured and simulated opposite-sign pion pair correlation functions for high and low sphericity intervals. The
C(q) in spherical events are relatively flat at unity, while the low sphericity correlation functions exhibit a very pronounced slope. This finding supports previous assumptions about the mini-jet origin of background correlations in interferometry analyses and demonstrates that PYTHIA describes two-pion correlations well in the absence of Bose-Einstein correlations.

Abstract: An improved value for the lifetime of the hypertriton has been obtained using the data sample of Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV collected by the ALICE experiment at the LHC. The (anti-)hypertriton has been identified via its charged two-body mesonic decay channel and the lifetime has been determined with an exponential fit to the d$N$/d($c$t) spectrum. The measured value, $\tau$ = 242$^{+34}_{-38}$ (stat.) $\pm$ 17 (syst.) ps, is in agreement within 1$\sigma$ with the free $\Lambda$ lifetime. This result is compatible with all the available theoretical predictions, thus contributing to the solution of the longstanding hypertriton lifetime puzzle.

Abstract: This work presents the first experimental observation of the attractive strong interaction between a proton and a multi-strange baryon (hyperon) $\Xi^-$. The result is extracted from two-particle correlations of combined p$-\Xi^{-}$ $\oplus$ $\overline{\mathrm{p}}-\overline{\Xi}^{+}$ pairs measured in p--Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$\,TeV at the LHC with ALICE. The measured correlation function is compared with the prediction obtained assuming only an attractive Coulomb interaction and a standard deviation in the range $[3.9, 4.7] $ is found. Since the measured p$-\Xi^{-}$ $\oplus$ $\overline{\mathrm{p}}-\overline{\Xi}^{+}$ correlation is significantly enhanced with respect to the Coulomb prediction, the presence of an additional, strong, attractive interaction is evident. The data are compatible with recent lattice calculations by the HAL-QCD Collaboration, with a standard deviation in the range $ [1.8, 2.8]$. The lattice potentials predict a shallow repulsive $\Xi^-$ interaction potential within pure neutron matter at saturation densities and this implies stiffer equations of state for neutron-rich matter including hyperons. Implications of the strong interaction for the modeling of neutron stars are discussed.

Abstract: CERN-LHC. Inclusive J/$\psi$ production is studied in minimum-bias proton-proton collisions at a centre-of-mass energy of $\sqrt{s} = 5.02$ TeV by ALICE at the CERN LHC. The measurement is performed at mid-rapidity ($|y| < 0.9$) in the dielectron decay channel down to zero transverse momentum $p_{\rm T}$, using a data sample corresponding to an integrated luminosity of $19.4 \pm 0.4 $ nb$^{-1}$. The measured $p_{\rm T}$-integrated inclusive J/$\psi$ production cross section is $\text{d}\sigma/\text{d}y = 5.64 \pm 0.22 (\text{stat.}) \pm 0.33 (\text{syst.}) \pm 0.12 (\text{lumi.})$ $\mu$b. The $p_{\rm T}$-differential cross section $\text{d}^2\sigma/\text{d}p_{\rm T}\text{d}y$ is measured in the $p_{\rm T}$ range 0$-$10 GeV/$c$ and compared with state-of-the-art perturbative QCD calculations. The J/$\psi$ $\langle p_{\rm T} \rangle$ and $\langle p_{\rm T}^2 \rangle$ are extracted and compared with results obtained at other collision energies.

Abstract: 'CERN-LHC.

The results were obtained in an extended transverse momentum interval, $2 < p_{\rm T} < 20$ GeV/$c$, and with an improved precision compared to previous measurements performed in the same rapidity interval at centre-of-mass energies $\sqrt{s} = 2.76$ and $7$ TeV. The $p_{\rm T}$- and $y$-differential production cross sections as well as the $p_{\rm T}$-differential production cross section ratios between different centre-of-mass energies and different rapidity intervals are described, within experimental and theoretical uncertainties, by predictions based on perturbative QCD.'

Abstract: Measurements are presented of the differential cross sections for Z bosons produced in proton-proton collisions at sqrt(s) = 13 TeV and decaying to muons and electrons. The data analyzed were collected in 2016 with the CMS detector at the LHC and correspond to an integrated luminosity of 35.8 fb-1. The measured fiducial inclusive product of cross section and branching fraction agrees with next-to-next-to-leading order quantum chromodynamics calculations. Differential cross sections of the transverse momentum pt, the optimized angular variable $\phi^{\scriptscriptstyle *}_\eta$, and the rapidity of lepton pairs are measured. The data are corrected for detector effects and compared to theoretical predictions using fixed order, resummed, and parton shower calculations. The uncertainties of the measured normalized cross sections are smaller than 0.5% for $\phi^{\scriptscriptstyle *}_\eta$ $<$ 0.5 and for pt $<$ 50 GeV.

Abstract: A search for exotic decays of the Higgs boson to a pair of light pseudoscalar particles a is performed under the hypothesis that one of the pseudoscalars decays to a pair of opposite sign muons and the other decays to two b quarks. Such signatures are predicted in a number of extensions of the standard model (SM), including next-to-minimal supersymmetry and two-Higgs-doublet models with an additional scalar singlet. The results are based on a data set of proton-proton collisions corresponding to an integrated luminosity of 35.9 fb-1, accumulated with the CMS experiment at the CERN LHC in 2016 at a centre-of-mass energy of 13TeV. No statistically significant excess is observed with respect to the SM backgrounds in the search region for pseudoscalar masses from 20GeV to half of the Higgs boson mass. Upper limits at 95% confidence level are set on the product of the production cross section and branching fraction, ranging from 5 to 33fb, depending on the pseudoscalar mass. Corresponding limits on the branching fraction, assuming the SM prediction for the Higgs cross section, are (1-7)*10-4.

Abstract: The measurement of the deuteron and anti-deuteron production in the rapidity range $-1 < y < 0$ as a function of transverse momentum and event multiplicity in p-Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV is presented. (Anti-)deuterons are identified via their specific energy loss $\mathrm{d}E/\mathrm{d}x$ and via their time-of-flight. Their production in p-Pb collisions is compared to pp and Pb-Pb collisions and is discussed within the context of thermal and coalescence models. The ratio of integrated yields of deuterons to protons (d/p) shows a significant increase as a function of the charged-particle multiplicity of the event starting from values similar to those observed in pp collisions at low multiplicities and approaching those observed in Pb-Pb collisions at high multiplicities. The mean transverse momenta are extracted from the deuteron spectra and the values are similar to those obtained for p and $\Lambda$ particles. Thus, deuteron spectra do not follow mass ordering.This behaviour is in contrast to the trend observed for non-composite particles in p-Pb collisions. In addition, the production of the rare $^{3}{\mathrm{He}}$ and $^{3}\overline{\rm He}$ nuclei has been studied. The spectrum corresponding to all non-single diffractive p-Pb collisions is obtained in the rapidity window $-1 < y < 0$ and the $p_{\mathrm{T}}$-integrated yield d$N$/d$y$ is extracted. It is found that the yields of protons, deuterons, and $^{3}{\mathrm{He}}$, normalised by the spin degeneracy factor, follow an exponential decrease with mass number.

and a photon in association with two jets in proton-proton collisions at sqrt(s) = 13 TeV.
The Z boson candidates are selected through their decay into a pair of electrons or muons.
The process of interest, electroweak Z gamma jj production, is isolated by selecting
events with a large dijet mass and a large pseudorapidity gap between the two jets.
The measurement is based on data collected with the CMS detector in 2016 at a center-of-mass
energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb−1.
The observed significance of the signal is 3.9 standard deviations, where a significance of
5.2 standard deviations is expected in the standard model predictions.
The results are combined with previously published CMS results based on sqrt(s)=8 TeV data,
which leads to an observed (expected) significance of 4.7 (5.5) standard deviations.
The measured value of the fiducial cross section for the signal is reported.
Bounds are given on quartic vector boson interactions in the framework of dimension-8

Abstract: A measurement of the mass of the Higgs boson in the diphoton decay channel is presented. This analysis is based on 35.9 fb$^{-1}$ of proton-proton collision data collected during the 2016 LHC running period, with the CMS detector at a center-of-mass energy of 13 TeV. A refined detector calibration and new analysis techniques have been used to improve the precision of this measurement. The Higgs boson mass is measured to be $m_{H}$ = 125.78 +/- 0.26 GeV. This is combined with a measurement of $m_{H}$ already performed in the H to ZZ to 4l decay channel using the same data set, giving $m_{H}$ = 125.46 +/- 0.16 GeV. This result, when further combined with an earlier measurement of $m_{H}$ using data collected in 2011 and 2012 with the CMS detector, gives a value for the Higgs boson mass of $m_{H}$ = 125.38 +/- 0.14 GeV. This is currently the most precise measurement of the mass of the Higgs boson.

Abstract: The production rates and the transverse momentum distribution of strange hadrons at mid-rapidity ($\left|y\right| < 0.5$) are measured in proton-proton collisions at $\sqrt{s}$ = 13 TeV as a function of the charged particle multiplicity, using the ALICE detector at the LHC. The production rates of $K^{0}_{s}$, $\Lambda$, $\Xi$, and $\Omega$ increase with the multiplicity faster than what is reported for inclusive charged particles. The increase is found to be more pronounced for hadrons with a larger strangeness content. Possible auto-correlations between the charged particles and the strange hadrons are evaluated by measuring the event-activity with charged particle multiplicity estimators covering different pseudorapidity regions. When comparing to lower energy results, the yields of strange hadrons are found to depend only on the mid-rapidity charged particle multiplicity. Several features of the data are reproduced qualitatively by general purpose QCD Monte Carlo models that take into account the effect of densely-packed QCD strings in high multiplicity collisions. However, none of the tested models reproduce the data quantitatively. This work corroborates and extends the ALICE findings on strangeness production in proton-proton collisions at 7 TeV.

Abstract: The study of the strength and behaviour of the antikaon-nucleon ($\mathrm{\overline{K}N}$) interaction constitutes one of the key focuses of the strangeness sector in low-energy Quantum Chromodynamics (QCD). In this letter a unique high-precision measurement of the strong interaction between kaons and protons, close and above the kinematic threshold, is presented. The femtoscopic measurements of the correlation function at low pair-frame relative momentum of (K$^+$ p $\oplus$ K$^-$ $\overline{\mathrm{p}}$ ) and ( K$^-$ p $\oplus$ K$^+$ $\overline{\mathrm{p}}$) pairs measured in pp collisions at $\sqrt{s}$\s\ = 5, 7 and 13 TeV are reported. A structure observed around a relative momentum of 58~MeV/$c$ in the measured correlation function of ( K$^-$ p $\oplus$ K$^+$ $\overline{\mathrm{p}}$) with a significance of 4.4 $\sigma$ constitutes the first experimental evidence for the opening of the $(\mathrm{\overline{K}^0 n} \oplus \mathrm{K^0 \overline{n}})$ isospin breaking channel due to the mass difference between charged and neutral kaons. The measured correlation functions have been compared to J\"ulich and Kyoto models in addition to the Coulomb potential. The high-precision data at low relative momenta presented in this work prove femtoscopy to be a powerful complementary tool to scattering experiments and provide new constraints above the $\mathrm{\overline{K}N}$ threshold for low-energy QCD chiral models.

Measurements of inclusive jet spectra in pp and central Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV;ALICE Collaboration;2020;HEPData


Abstract: In this letter, the production of deuterons and anti-deuterons in pp collisions at $\sqrt{s}$ = 7 TeV is studied as a function of the charged-particle multiplicity density at mid-rapidity with the ALICE detector at the LHC. Production yields are measured at mid-rapidity in five multiplicity classes and as a function of the deuteron transverse momentum (pT). The measurements are discussed in the context of hadron-coalescence models. The coalescence parameter B2, extracted from the measured spectra of (anti-)deuterons and primary (anti-)protons, exhibits no significant pT-dependence for pT < 3 GeV/c, in agreement with the expectations of a simple coalescence picture. At fixed transverse momentum per nucleon, the B2 parameter is found to decrease smoothly from low multiplicity pp to Pb-Pb collisions, in qualitative agreement with more elaborate coalescence models. The measured mean transverse momentum of (anti-)deuterons in pp is not reproduced by the Blast-Wave model calculations that simultaneously describe pion, kaon and proton spectra, in contrast to central Pb-Pb collisions. The ratio between the pT-integrated yield of deuterons to protons, d/p, is found to increase with the charged-particle multiplicity, as observed in inelastic pp collisions at different centre-of-mass energies. The d/p ratios are reported in a wide range, from the lowest to the highest multiplicity values measured in pp collisions at the LHC.

CERN-LHC. The cross section of top quark pair production is measured in the dilepton final state with one tau lepton decaying hadronically.
The data sample corresponds to an integrated luminosity of 35.9 inverse femtobarns
collected in proton-proton collisions at sqrt(s) = 13 TeV in 2016 with the CMS detector.
The ratio of the cross sections in the lepton-tau and light dilepton final states
and the ratio of the partial width to the total decay width of the top quark are also measured.

The production of isolated photons in PbPb and pp collisions at $\sqrt{s_\mathrm{NN}} =$ 5.02 TeV;CMS Collaboration;2020;HEPData


Abstract: The strong Coulomb field created in ultrarelativistic heavy ion collisions is expected to produce a rapidity-dependent difference ($\Delta v_2$) in the second Fourier coefficient of the azimuthal distribution (elliptic flow, $v_2$) between $D^0$ ($\overline{u}c$) and $\overline{D}^0$ ($u\overline{c}$) mesons. Motivated by the search for evidence of this field, the CMS detector at the LHC is used to perform the first measurement of $\Delta v_2$. The rapidity-averaged value is found to be $<\Delta v_2>=0.001\pm0.001(stat)\pm0.003(syst)$ in PbPb collisions at $\sqrt{s_{NN}}=5.02~TeV$. In addition, the influence of the collision geometry is explored by measuring the $D^0$ and $\overline{D}^0$ mesons $v_2$ and triangular flow coefficient ($v_3$) as functions of rapidity, transverse momentum ($p_T$), and event centrality (a measure of the overlap of the two Pb nuclei). A clear centrality dependence of prompt $D^0$ meson $v_2$ values is observed, while the $v_3$ is largely independent of centrality. These trends are consistent with expectations of flow driven by the initial-state geometry.

Search for strong electric fields in PbPb collisions at $\sqrt{s_\mathrm{NN}} =$ 5.02 TeV using azimuthal anisotropy of prompt $\mathrm{D}^0$ and $\overline{\mathrm{D}}^0$ mesons;CMS Collaboration;2021;HEPData


Abstract: This paper presents the first measurements of the charge independent (CI) and charge dependent (CD) two-particle transverse momentum correlators $G_{2}^{\rm CI}$ and $G_{2}^{\rm CD}$ in Pb--Pb collisions at $\sqrt{s_{\text{NN}}} = 2.76\;\text{TeV}$ by the ALICE collaboration. The correlators are measured as a function of pair separation in pseudorapidity ($\Delta \eta$) and azimuth ($\Delta \varphi$) and as a function of collision centrality.The correlator $G_{2}^{\rm CI}$ exhibits a longitudinal broadening while undergoing a monotonic azimuthal narrowing from peripheral to central collisions. By contrast, $G_{2}^{\rm CD}$ exhibits a narrowing along both dimensions towards central events. These features are not reproduced by models such as HIJING and AMPT. However, the observed narrowing of the correlators is expected to result from the stronger transverse flow profiles produced in more central collisions and the longitudinal broadening is predicted to be sensitive to momentum currents and the shear viscosity per unit of entropy density $\eta/s$ of the matter produced in the collisions. The observed broadening is found to be consistent with the hypothesized lower bound of $\eta/s$ and is in qualitative agreement with values obtained from anisotropic flow measurements.
