Abstract: We measure the two-point and three-point energy correlator jet substructure observables (E2C and E3C), using LHC 13 TeV data collected by the CMS experiment.The jets are clustered by anti-$k_\mathrm{t}$ algorithm with $R=0.4$ in a phase space region with jet $p_\mathrm{T}$ from 97 GeV up to 1.8 TeV and $|y|<2.1$.The E2C and E3C distribution are measured in multiple jet transverse momentum regions, they show a sharp transition from the noninteger scaling behavior charaterizing the quantum interactions of quarks and gluons to an integer power law reflective of classical noninteracting hadrons.The ratio of E3C/E2C is directly proportional to the strong coupling constant $\alpha_S$, and the slopes of the ratio distribution consistent with the expected decrease of $\alpha_S$ with increasing energy due to asymptotic freedom.The ratio between E3C and E2C are compared to theoretical predictions with all-orders resummation at next-to-next-to-leading logarithmic accuracy matched to a fixed-order next-to-leading order calculation, yielding an $\alpha_S (m_Z)$ value of $0.1229^{+0.0040}_{-0.0050}$.This is the most precise extraction of $\alpha_S (m_Z)$ using jet substructure observables to date.

Search for long-lived heavy neutrinos in the decays of B mesons produced in proton-proton collisions at $\sqrt{s}$ = 13 TeV;CMS Collaboration;2024;HEPData


Abstract: A search is presented for the decay of the 125 GeV Higgs boson (H) to a pair of new light pseudoscalar bosons (a), followed by the prompt decay of each a boson to a bottom quark-antiquark pair, $\textrm{H} \rightarrow$ aa $\rightarrow$ bbbb. The analysis is performed using a data sample of proton-proton collisions collected with the CMS detector at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 138 $\textrm{fb}^{-1}$. To reduce the background from standard model processes, the search requires the Higgs boson to be produced in association with a leptonically decaying W or Z boson. The analysis probes the production of new light bosons in a $15 < \textrm{m}_{a} < 60$ GeV mass range. Assuming the standard model predictions for the Higgs boson production cross sections for pp $\rightarrow$ WH and ZH, model independent upper limits at 95% confidence level are derived for the branching fraction $\mathcal{B}(\textrm{H} \rightarrow$ aa $\rightarrow$ bbbb). The combined WH and ZH observed upper limit on the branching fraction ranges from 1.10 for $\textrm{m}_{a} = 20$ GeV to 0.36 for $\textrm{m}_{a} = 60$ GeV, complementing other measurements in the $\mu\mu\tau\tau$, $\tau\tau\tau\tau$ and bb$\ell\ell$ ($\ell=\mu, \tau$) channels.

Abstract: Results of a search for Higgs boson pair (HH) production with one Higgs boson decaying to two bottom quarks and the other to two W bosons are presented. The search is done using proton-proton collisions data at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 138 fb$^{−1}$ recorded by the CMS detector at the LHC from 2016 to 2018. The final states considered include at least one leptonically decaying W boson. No evidence for the presence of a signal is observed and corresponding upper limits on the HH production cross section are derived. The limit on the inclusive cross section of the nonresonant HH production, assuming that the distributions of kinematic observables are as expected in the standard model (SM), is observed (expected) to be 14 (18) times the value predicted by the SM, at 95% confidence level. The limits on the cross section are also shown as functions of various Higgs boson coupling modifiers, and anomalous Higgs boson coupling scenarios. In addition, limits are set on the resonant HH production via spin-0 and spin-2 resonances within the mass range 250–900 GeV.

Abstract: A measurement of the production cross section of a Higgs boson with transverse momentum greater than 250 GeV is presented where the Higgs boson decays to a pair of $\tau$ leptons. It is based on proton-proton collision data collected by the CMS experiment at the CERN LHC at a center-of-mass energy of 13 TeV. The data sample corresponds to an integrated luminosity of 138 fb$^{-1}$. Because of the large transverse momentum of the Higgs boson the $\tau$ leptons from its decays are boosted and produced spatially close, with their decay products overlapping. Therefore, a dedicated algorithm was developed to reconstruct and identify them. The observed (expected) significance of the measured signal with respect to the standard model background-only hypothesis is 3.5 (2.2) standard deviations. The product of the production cross section and branching fraction is measured to be $1.64^{+0.68}_{-0.54}$ times the standard model expectation. The fiducial differential production cross section is also measured as functions of the Higgs boson and leading jet transverse momenta. This measurement extends the probed large-transverse-momentum region beyond 600 GeV.

Abstract: A search for Higgs boson pair (HH) production in association with a vector boson V (W or Z boson) is presented.The search is based on proton-proton (pp) collision data at a center-of-mass energy of 13 TeV,collected with the CMS detector at the LHC, corresponding to an integrated luminosity of $138 fb^{-1}$.The processes in this search include $pp \rightarrow ZHH$ and $pp \rightarrow WHH$ production. All hadronic decaysand leptonic decays of V bosons involving electrons, muons, and neutrinos are considered.Pairs of Higgs bosons are searched for in the $b\bar{b}b\bar{b}$ decay channel.An observed (expected) upper limit at 95\% confidence level of VHH production cross section is set at 294 (124) times the standard model prediction.Constraints are also set on the modifiers of the Higgs boson trilinear self-coupling, $\kappa_{\lambda}$, assuming $\kappa_{2V} = 1$ (SM)and vice versa on the coupling of two Higgsbosons with two vector bosons, $\kappa_{2V}$. The observed (expected) 95\% confidence intervals of these coupling modifiersare $-37.7<\kappa_{\lambda}<37.2$ ($-30.1<\kappa_{\lambda}<28.9$) and $-12.2<\kappa_{2V}<13.5$ ($-7.2<\kappa_{2V}<8.9$), respectively.

Abstract: A measurement is presented of the ratio observable $R_{\Delta\phi}(p_\mathrm{T})$ that provides a measure of the azimuthal correlations among jets with large transverse momentum $p_\mathrm{T}$. The $R_{\Delta\phi}(p_\mathrm{T})$ variable is measured in multijet events over the $p_\mathrm{T} = 360\mathord{-}3170~\mathrm{GeV}$ range based on data collected by the CMS experiment in proton-proton collisions at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of $134~\mathrm{fb}^{-1}$. The results are compared with predictions from Monte Carlo parton-shower event generator simulations, as well as with fixed-order perturbative quantum chromodynamics (pQCD) predictions at next-to-leading-order (NLO) accuracy obtained with different parton distribution functions (PDFs) and corrected for nonperturbative and electroweak effects. Data and theory agree within uncertainties. From the comparison of the measured distribution with the pQCD prediction obtained with the NNPDF3.1 NLO PDFs, the strong coupling constant at the Z boson mass scale is $\alpha_\mathrm{S}(M_\mathrm{Z}) = 0.1177 \pm 0.0013\, \text{(exp)} _{-0.0073}^{+0.0116} \, \text{(theo)} = 0.1177_{-0.0074}^{+0.0117}$, where the total uncertainty is dominated by the scale dependence of the fixed-order predictions. A test of the running of $\alpha_\mathrm{S}(Q)$ in the TeV region shows no deviation from the expected NLO pQCD behaviour.

Abstract: The first search for the Z boson decay to $\tau\tau\mu\mu$ at the CERN LHC is presented, based on data collected by the CMS experiment at the LHC in proton-proton collisions at a center-of-mass energy of $13\,\text{TeV}$ and corresponding to an integrated luminosity of $138\,\text{fb}^{-1}$. The data are compatible with the predicted background. For the first time, an upper limit at the $95\%$ confidence level of 6.9 times the standard model expectation is placed on the ratio of the ${\text{Z}\to\tau\tau\mu\mu}$ to ${\text{Z}\to4\mu}$ branching fractions. Limits are also placed on the six flavor-conserving four-lepton effective-field-theory operators involving two muons and two tau leptons, for the first time testing all such operators.

Abstract: This Letter presents the first measurements of the groomed jet radius $R_{\mathrm{g}}$ and the jet girth $g$ in events with an isolated photon recoiling against a jet in lead-lead (PbPb) and proton-proton (pp) collisions at the LHC at a nucleon-nucleon center-of-mass energy of 5.02 TeV. The observables $R_{\mathrm{g}}$ and $g$ provide a quantitative measure of how narrow or broad a jet is. The analysis uses PbPb and pp data samples with integrated luminosities of 1.7~nb$^{-1}$ and 301~pb$^{-1}$, respectively, collected with the CMS experiment in 2018 and 2017. Events are required to have a photon with transverse momentum $p_{\mathrm{T}}^{\gamma} > 100$~GeV and at least one jet back-to-back in azimuth with respect to the photon and with transverse momentum $p_{\mathrm{T}}^{\text{jet}}$ such that $p_{\mathrm{T}}^{\text{jet}}/p_{\mathrm{T}}^{\gamma} > 0.4$. The measured $R_{\mathrm{g}}$ and $g$ distributions are unfolded to the particle level, which facilitates the comparison between the PbPb and pp results and with theoretical predictions. It is found that jets with $p_{\mathrm{T}}^{\text{jet}}/p_{\mathrm{T}}^{\gamma} > 0.8$, i.e, those that closely balance the photon $p_{\mathrm{T}}^{\gamma}$, are narrower in PbPb than in pp collisions. Relaxing the selection to include jets with $p_{\mathrm{T}}^{\text{jet}}/p_{\mathrm{T}}^{\gamma} > 0.4$ reduces the narrowing of the angular structure of jets in PbPb relative to the pp reference. This shows that selection bias effects associated with jet energy loss play an important role in the interpretation of jet substructure measurements.

Abstract: In this Letter, measurements of the long-range correlations in p--Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$~TeV are extended to a pseudorapidity gap of $\Delta\eta\sim$8 between particles using the ALICE forward multiplicity detectors. After suppressing non-flow correlations, e.g., from jet and resonance decays, the ridge structure is observed to persist up to a very large gap of $\Delta\eta\sim$8 for the first time in p--Pb collisions. This shows that the collective flow-like correlations extend over an extensive pseudorapidity range also in small collision systems such as p--Pb collisions. The pseudorapidity dependence of the second-order anisotropic flow coefficient, \Veta, is extracted from the long-range correlations. The $v(\eta)$ results are presented for a wide pseudorapidity range of $-3.1 <\eta< 4.8$ in various centrality classes in p--Pb collisions. To gain a comprehensive understanding of the source of anisotropic flow in small collision systems, the $v(\eta)$ measurements are compared with hydrodynamic and transport model calculations. The comparison suggests that the final-state interactions play a dominant role in developing the anisotropic flow in small collision systems.

Abstract: The ALICE Collaboration reports measurements of the semi-inclusive distribution of charged-particle jets recoiling from a high transverse momentum (high $p_\mathrm{T}$) charged hadron, in pp and central Pb--Pb collisions at center of mass energy per nucleon--nucleon collision $\sqrt{s_\mathrm{NN}}=5.02$ TeV. The large uncorrelated background in central Pb--Pb collisions is corrected using a data-driven statistical approach, which enables precise measurement of recoil jet distributions over a broad range in $p_\mathrm{T,ch jet}$ and jet resolution parameter $R$. Recoil jet yields are reported for $R=$ 0.2, 0.4, and 0.5 in the range $7

Abstract: A search for a new charged particle $\text{X}$ with mass between 0.3 and 2.0$~\mathrm{TeV}$ decaying to a W boson and a photon using proton-proton collision data at a center-of-mass energy of $13~\mathrm{TeV}$, collected by the CMS experiment and corresponding to an integrated luminosity of $138~\mathrm{fb}^{-1}$, is presented. Particle $\text{X}$ has electric charge $\pm1$ and is assumed to have spin 0. The search is performed using the electron and muon decays of the W boson. No significant excess above the predicted background is observed. The upper limit at $95\%$ confidence level on the product of the $\text{X}$ production cross section and its branching fraction to a W boson and a photon is found to be 94 (137)$~\mathrm{fb}$ for a $0.3~\mathrm{TeV}$ resonance and 0.75 (0.81)$~\mathrm{fb}$ for a $2.0~\mathrm{TeV}$ resonance, for an $\text{X}$ width-to-mass ratio of 0.01$\%$ (5$\%$). A statistical combination with an earlier study based on the hadronic decay mode of the W boson is also performed, and the upper limit at 95$\%$ confidence level for a 2.0$~\mathrm{TeV}$ resonance is reduced to 0.50 (0.63)$~\mathrm{fb}$ for an $\text{X}$ width-to-mass ratio of 0.01$\%$ (5$\%$).

Abstract: Nuclear medium effects on $\text{B}^+$ meson production are studied using the binary-collision scaled cross section ratio between events of different charged-particle multiplicities from proton-lead collisions. Data, collected by the CMS experiment in 2016 at a nucleon-nucleon center-of-mass energy of $\sqrt{s_{NN}} = 8.16\,$TeV, corresponding to an integrated luminosity of 175\nbinv, were used. The scaling factors in the ratio are determined using a novel approach based on the Z$\,\to\mu^{-}\mu^{+}$ cross sections measured in the same events. The scaled ratio for $\text{B}^+$ is consistent with unity for all event multiplicities, putting stringent constraints on nuclear modification for heavy flavor.

Abstract: A search for dark matter (DM) particles produced in association with bottom quarks is presented. The analysis uses proton-proton collision data at a center-of-mass energy of $\sqrt{s}=$13 TeV, corresponding to an integrated luminosity of 138 fb$^{-1}$. The search is performed in the final state with large missing transverse momentum and a pair of jets originating from bottom quarks. No significant excess of data is observed with respect to the standard model expectation. Results are interpreted in the context of a type-II two-Higgs-doublet model with an additional light pseudoscalar (2HDM+a). An upper limit is set on the mass of the lighter pseudoscalar, excluding masses up to 260 GeV at $95\%$ confidence level. This is the first search at the LHC to probe DM produced in association with two nonresonant bottom quarks in the 2HDM+a model. Sensitivity to the parameter space with the ratio of the vacuum expectation values of the two Higgs doublets, $\tan\beta$, greater than 15 is achieved, capitalizing on the enhancement of couplings between pseudoscalars and bottom quarks with high $\tan\beta$.

Abstract: An analysis of the production of a Higgs boson ($H$) in association with a top quark-antiquark pair ($t\bar{t}H$) or a single top quark ($tH$) is presented. The Higgs boson decay into a bottom quark-antiquark pair ($H \to b\bar{b}$) is targeted, and three different final states of the top quark decays are considered, defined by the number of leptons (electrons or muons) in the event. The analysis utilises proton-proton collision data collected at the CERN LHC with the CMS experiment at $\sqrt{s} = 13$ TeV in 2016-2018, which correspond to an integrated luminosity of 138 fb${}^{-1}$. The observed $t\bar{t}H$ production rate relative to the standard model expectation is $0.33 \pm 0.26=0.33 \pm 0.17(\text{stat}) \pm 0.21 (\text{syst})$. Additionally, the $t\bar{t}H$ production rate is determined in intervals of Higgs boson transverse momentum. An upper limit at 95% confidence level is set on the $tH$ production rate of 14.6 times the standard model prediction, with an expectation of $19.3^{+9.2}_{-6.0}$. Finally, constraints are derived on the strength and structure of the coupling between the Higgs boson and the top quark from simultaneous extraction of the $t\bar{t}H$ and $tH$ production rates, and the results are combined with those obtained in other Higgs boson decay channels.

Abstract: Title Stairway to discovery a report on the CMS programme of cross section measurements from millibarns to femtobarns Abstract The Large Hadron Collider at CERN, delivering proton-proton collisions at much higher energies and far higher luminosities than previous machines, has enabled a comprehensive programme of measurements of the standard model (SM) processes by the CMS experiment. These unprecedented capabilities facilitate precise measurements of the properties of a wide array of processes, the most fundamental being cross sections. The discovery of the Higgs boson and the measurement of its mass became the keystone of the SM. Knowledge of the mass of the Higgs boson allows precision comparisons of the predictions of the SM with the corresponding measurements. These measurements span the range from one of the most copious SM processes, the total inelastic cross section for proton-proton interactions, to the rarest ones, such as Higgs boson pair production. They cover the production of Higgs bosons, top quarks, single and multibosons, and hadronic jets. Associated parameters, such as coupling constants, are also measured. These cross section measurements can be pictured as a descending stairway, on which the lowest steps represent the rarest processes allowed by the SM, some never seen before.

Abstract: The production yields of the $\Sigma(1385)^{\pm}$ and $\Xi(1530)^{0}$ resonances are measured in pp collisions at $\sqrt{\it{s}}=13$~Te\kern-.1emV with ALICE. The measurements are performed as a function of the charged particle multiplicity $\langle\mathrm{d}N_\mathrm{ch}/\mathrm{d}\eta\rangle$, which is related to the energy density produced in the collision. The results include transverse momentum ($p_\mathrm{T}$) distributions, $p_\mathrm{T}$-integrated yields, mean transverse momenta of $\Sigma(1385)^{\pm}$ and $\Xi(1530)^{0}$, as well as ratios of the $p_\mathrm{T}$-integrated resonance yields relative to yields of other hadron species. The $\Sigma(1385)^{\pm}/\pi^{\pm}$ and $\Xi(1530)^{0}/\pi^{\pm}$ yield ratios are consistent with the trend of the enhancement of strangeness production from low to high multiplicity pp collisions, which was previously observed for strange and multi-strange baryons. The yield ratio between the measured resonances and the long-lived baryons with the same strangeness content exhibits a hint of a mild increasing trend at low multiplicity, despite too large uncertainties to exclude the flat behaviour. The results are compared to predictions from models such as EPOS-LHC and $\rm{PYTHIA\,\,8}$ with Rope shoving. The latter provides the best description of the multiplicity dependence of the $\Sigma(1385)^{\pm}$ and $\Xi(1530)^{0}$ production in pp collisions at $\sqrt{\it{s}}=13$~Te\kern-.1emV.

Abstract: A search is presented for a heavy resonance decaying into a Z boson and a Higgs (H) boson. The analysis is based on data from proton-proton collisions at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity of 138 $fb^{-1}$, recorded with the CMS experiment in the years 2016-2018. Resonance masses between 1.4 and 5 TeV are considered, resulting in large transverse momenta of the Z and H bosons. Final states that result from Z boson decays to pairs of electrons, muons, or neutrinos are considered. The H boson is reconstructed as a single large-radius jet, recoiling against the Z boson. Machine-learning flavour-tagging techniques are employed to identify decays of a Lorentz-boosted H boson into pairs of charm or bottom quarks, or into four quarks via the intermediate $H\to W W^{*}$ and $ZZ^{*}$ decays. The analysis targets H boson decays that were not generally included in previous searches using the $H\to b\overline{b}$ channel. Compared with previous analyses, the sensitivity for high resonance masses is improved significantly in the channel where at most one b quark is tagged.

Abstract: The forward-backward asymmetry in Drell--Yan production and the effective leptonic electroweak mixing angle are measured in proton-proton collisions at $\sqrt{s} = 13$\TeV, collected by the CMS experiment and corresponding to an integrated luminosity of 138\fbinv. The measurement uses both dimuon and dielectron events, and is performed as a function of the dilepton mass and rapidity. The unfolded angular coefficient \afour is also extracted, as a function of the dilepton mass and rapidity.Using the CT18Z set of parton distribution functions, we obtain $\sineff = 0.23157 \pm 0.00031$, where the uncertainty reflects the statistical and systematic (experimental and theoretical) contributions.The measured value agrees with the standard model fit result to global experimental data.The measured value agrees with the standard model fit result to global experimental data.This is the most precise \sineff measurement at a hadron collider, with a precision comparable to the results obtained at LEP and SLD.

Abstract: A measurement of the Higgs boson mass and width via its decay to two Z bosons is presented. Proton-proton collision data collected by the CMS experiment, corresponding to an integrated luminosity of $138~\mathrm{fb}^{-1}$ at a center-of-mass energy of $13~\mathrm{TeV}$ is used. The invariant mass distribution of four leptons in the on-shell Higgs boson decay is used to measure its mass and contrain its width. This yields the most precise single measurement of the Higgs boson mass to date, $125.04 \pm 0.12~\mathrm{GeV}$, and an upper limit on the width $\Gamma_\mathrm{H} < 330~\mathrm{MeV}$ at $95\%$ confidence level. A combination of the on- and off-shell Higgs boson production decaying to four leptons is used to determine the Higgs boson width.This result is combined with a previous CMS analysis of the off-shell Higgs boson production with decay to two leptons and two neutrinos, giving a measured Higgs boson width of $3.0\,^{+2.0}_{-1.5}~\mathrm{MeV}$, in agreement with the standard model prediction of $4.1~\mathrm{MeV}$. The strength of the off-shell Higgs boson production is also reported. The scenario of no off-shell Higgs boson production is excluded at a confidence level corresponding to 3.8 standard deviations.

Abstract: Investigating the nature of the K$^*_0(700)$ state with $\pi^\pm$ K$^0_{\rm S}$ correlations at the LHC. -- The first measurements of femtoscopic correlations with the particle pair combinations $\pi^\pm$ K$^0_{\rm S}$ in pp collisions at $\sqrt{s}=13$ TeV at the Large Hadron Collider are reported by the ALICE experiment. Using the femtoscopic approach, it is shown that it is possible to study the elusive K$^*_0(700)$ particle that has been considered a tetraquark candidate for over forty years. Boson source parameters and final-state interaction parameters are extracted by fitting a model assuming a Gaussian source to the experimentally measured two-particle correlation functions. The final-state interaction is modeled through a resonant scattering amplitude, defined in terms of a mass and a coupling parameter, decaying into a $\pi^\pm$K$^0_{\rm S}$ pair. The extracted mass and Breit--Wigner width, derived from the coupling parameter, of the final-state interaction are found to be consistent with previous measurements of the K$^*_0(700)$. The small value and increasing behavior of the correlation strength with increasing source size support the hypothesis that the K$^*_0(700)$ is a four-quark state, i.e. a tetraquark state. This latter trend is also confirmed via a simple geometric model that assumes a tetraquark structure of the K$^*_0(700)$ resonance.

Abstract:
In this work K$^+$--d and p--d femtoscopic correlations measured in high multipicity proton--proton (pp) collisions at $\sqrt{s}=13$~TeV by the ALICE Collaboration at the Large Hadron Collider (LHC) are presented.
Deuterons are atomic nuclei composed of a neutron and a proton held together by the strong interaction. Unbound ensembles composed of a deuteron and a third nucleon have been investigated in the past using scattering experiments and they constitute a fundamental reference in nuclear physics to constrain nuclear interactions and the properties of nuclei. In this work K$^{+}$--d and p--d femtoscopic correlations measured by the ALICE Collaboration in proton--proton (pp) collisions at $\sqrt{s}=13$~TeV at the Large Hadron Collider (LHC) are presented. It is demonstrated that correlations in momentum space between deuterons and kaons or protons allow us to study three-hadron systems at distances comparable with the proton radius. The analysis of the K$^{+}$--d correlation shows that the relative distances at which deuterons and proton/kaons are produced are around 2 fm. The analysis of the p--d correlation shows that only a full three-body calculation that accounts for the internal structure of the deuteron can explain the data. In particular, the sensitivity of the observable to the short-range part of the interaction is demonstrated. These results indicate that correlations involving light nuclei in pp collisions at the LHC will also provide access to any three-body systems in the strange and charm sectors.

Abstract: A search for heavy, long-lived, charged particles with large ionization energy loss within the silicon tracker of the CMS experiment is presented. A data set of proton-proton collisions at a center of mass energy at $\sqrt{s} = 13~\mathrm{TeV}$, collected in 2017 and 2018 at the CERN LHC, corresponding to an integrated luminosity of $101~\mathrm{fb}^{-1}$, is used in this analysis. Two different approaches for the search are taken. A new method exploits the independence of the silicon pixel and strips measurements, while the second method improves on previous techniques using ionization to determine a mass selection. No significant excess of events above the background expectation is observed. The results are interpreted in the context of the pair production of supersymmetric particles, namely gluinos, top squarks, and tau sleptons, and of the Drell--Yan pair production of fourth generation ($\tau'$) leptons with an electric charge equal to or twice the absolute value of the electron charge ($e$). An interpretation of a $\mathrm{Z'}$ boson decaying to two $\tau'$ leptons with an electric charge equal to $2e$ is presented for the first time. The $95\%$ confidence upper limits on the production cross section are extracted for each of these hypothetical particles.

Abstract: A search for light long-lived particles decaying to displaced jets is presented, using a data sample of proton-proton collisions at a center-of-mass energy of $13.6~\mathrm{TeV}$, corresponding to an integrated luminosity of $34.7~\mathrm{fb^{-1}}$, collected with the CMS detector at the CERN LHC in 2022. Novel trigger, reconstruction, and machine-learning techniques were developed for and employed in this search. After all selections, the observations are consistent with the background predictions. Limits are presented on the branching fraction of the Higgs boson to long-lived particles that subsequently decay to quark pairs or tau lepton pairs. Up to a factor of 10 improvement is achieved over previous limits for models with long-lived particle masses smaller than $60~\mathrm{GeV}$ and proper decay lengths smaller than $1~\mathrm{m}$. The first constraints are placed on the fraternal twin Higgs and folded supersymmetry models, where the lower bounds on the top quark partner mass reach up to $350~\mathrm{GeV}$ for the fraternal twin Higgs model and $250~\mathrm{GeV}$ for the folded supersymmetry model.

Abstract: A search for heavy neutral gauge bosons (\PZpr) decaying to two tau leptons is performed in proton-proton collisions at $\sqrt{s}=13$~\TeV at the CERN LHC. The data were collected with the CMS detector and correspond to an integrated luminosity of 138~\fbinv. The observations are found to be in agreement with the expectation from standard model processes. Limits at 95\% confidence level are set on the cross section for production of a \PZpr boson times the branching fraction for its decay to a tau lepton pair, as functions of the \PZpr boson mass. For a narrow resonance in the sequential standard model scenario, a \PZpr boson with mass below 3.5\TeV is excluded. This is the most stringent limit to date from this type of search.

Abstract: A search is presented for the pair production of new heavy resonances, each decaying into a top quark or antiquark and a gluon. The analysis uses data recorded with the CMS detector from proton-proton collisions at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 138 $fb^{-1}$. Events with one muon or electron, multiple jets, and missing transverse momentum are selected. After using a deep neural network to enrich the data sample with signal-like events, distributions in the scalar sum of the transverse momenta of all reconstructed objects are analyzed in search for a signal. No significant deviations from the standard model predictions are found. Upper limits at 95% confidence level are set on the product of cross section and branching fraction squared for the pair production of excited top quarks in the $t^{*} \rightarrow tg$ decay channel. The upper limits range from 0.12 $pb$ to 0.8 $fb$ for a $t^{*}$ with spin-1/2 and from 0.015 $pb$ to 1.0 $fb$ for a t^{*} with spin-3/2. These correspond to mass exclusion limits up to 1050 and 1700 GeV for spin-1/2 and spin-3/2 $t^{*}$ particles, respectively.

Abstract: A first search for a heavy neutral spin-1 gauge boson ($Z'$) produced via vector boson fusion processes and decaying to tau leptons is presented. The analysis considers scenarios in which the $Z'$ boson has nonuniversal fermion couplings that favor higher-generation fermions. These scenarios represent a physics phase space not yet fully explored at the LHC. The analysis is performed using LHC data at $\sqrt{s}$ = 13 TeV, collected from 2016 to 2018 and corresponding to an integrated luminosity of 138 fb$^{-1}$. The data are consistent with the standard model expectation. Upper limits are set on the product of the cross section for production of the $Z'$ boson and its branching fraction to $\tau\tau$ or $WW$. As a consequence, masses below up to 2.45 TeV are excluded at 95$\%$ confidence level, depending on the $Z'$ coupling to weak bosons.

Abstract: This paper presents a model-agnostic search for narrow resonances in the dijet final state in the mass range 1.8--6 TeV.The signal is assumed to produce jets with substructure atypical of jets initiated by light quarks or gluons, with minimal additional assumptions.Search regions are obtained by utilizing multivariate machine-learning methods to select jets with anomalous substructure.A collection of complementary anomaly detection methods---based on unsupervised, weakly supervised, and semisupervised algorithms---are used in order to maximize the sensitivity to unknown new physics signatures.These algorithms are applied to data corresponding to an integrated luminosity of 138 fb$-1$, recorded by the CMS experiment at the LHC, at a center-of-mass energy of 13 TeV.No significant excesses above background expectations are seen. Exclusion limits are derived on the production cross section of benchmark signal models varying in resonance mass, jet mass, and jet substructure.Many of these signatures have not been previously sought, making several of the limits reported on the corresponding benchmark models the first ever. When compared to benchmark inclusive and substructure-based search strategies, the anomaly detection methods are found to significantly enhance the sensitivity to a variety of models.

Abstract: The first search is presented for vector-like leptons (VLLs) in the context of the "4321 model", an ultraviolet-complete model with the potential to explain existing PB physics measurements that are in tension with standard model predictions. The analyzed data, corresponding to an integrated luminosity of $96.5~\textrm{fb}^{-1}$, were recorded in 2017 and 2018 with the CMS detector at the LHC in proton-proton collisions at $\sqrt{s}=13\,\mathrm{TeV}$. Final states with $\geq3$ b-tagged jets and two third-generation leptons ($\tau\tau$, $\tau\nu_{\tau}$, or $\nu_{\tau}\nu_{\tau}$) are considered. Upper limits are derived on the VLL production cross section in the VLL mass range 500-1050 GeV. The maximum likelihood fit prefers the presence of signal at the level of 2.8 standard deviations, for a representative VLL mass point of $600\,\textrm{GeV}$. As a consequence, the observed upper limits are approximately double the expected limits.

Measurement of W-boson production at forward rapidity in p-Pb collisions at $\sqrt{s_{NN}} =$ 8.16 TeV and Pb-Pb collisions at $\sqrt{s_{NN}} =$ 5.02 TeV. The measurement is done in the muon decay channel.

The fiducial region is defined by
- $\eta$ (pseudorapidity) of muons in $-4.0 < \eta < -2.5$ in the laboratory frame and ALICE reference system
- $p_{\rm T}$ (transverse momentum) of muons larger than 10 GeV/$c$

For Pb-Pb collisions the laboratory frame and cms frame coincide. For p-Pb collisions the nucleon-nucleon cms is boosted with respect to the laboratory frame by $\Delta y_{cms} = \pm 0.465$

Abstract: The first measurements of elliptic flow of $\mathrm{\pi}^{\pm}$, $\mathrm{K}^{\pm}$, $\mathrm{p}+\bar{\mathrm{p}}$, $\mathrm{K_{S}^{0}}$, $\Lambda+\bar{\Lambda}$, $\mathrm{\phi}$, $\mathrm{\Xi^{\mp}}$, and $\mathrm{\Omega^{\mp}}$ using multiparticle cumulants in Pb--Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV are presented. Results obtained with two- ($v_2\{2\}$) and four-particle cumulants ($v_2\{4\}$) are shown as a function of transverse momentum, $p_{\rm T}$, for various collision centrality intervals. Combining the data for both $v_2\{2\}$ and $v_2\{4\}$ also allows us to report the first measurements of the mean elliptic flow, elliptic flow fluctuations, and relative elliptic flow fluctuations for various hadron species. These observables probe the event-by-event eccentricity fluctuations in the initial state and the contributions from the dynamic evolution of the expanding quark--gluon plasma. The characteristic features observed in previous $p_{\rm T}$-differential anisotropic flow measurements for identified hadrons with two-particle correlations, namely the mass ordering at low $p_{\rm T}$ and the approximate scaling with the number of constituent quarks at intermediate $p_{\rm T}$, are similarly present in the four-particle correlations and the combinations of $v_2\{2\}$ and $v_2\{4\}$. In addition, a particle species dependence of flow fluctuations is observed that could indicate a significant contribution from final state hadronic interactions. The comparison between experimental measurements and CoLBT model calculations, which combine the various physics processes of hydrodynamics, quark coalescence, and jet fragmentation, illustrates their importance over a wide $p_{\rm T}$ range.

Abstract: This Letter presents the first measurement of the interaction between charm hadrons and nucleons.The two-particle momentum correlations of $\mathrm{pD^-}$ and $\mathrm{\overline{p}D^+}$ pairs are measured by the ALICE Collaboration in high-multiplicity pp collisions at $\sqrt{s} = 13$ TeV. The data are compatible with the Coulomb-only interaction hypothesis within $(1.1-1.5)\sigma$.Considering an attractive nucleon(N)$\overline{\mathrm{D}}$ strong interaction, in contrast to most model predictions which suggest an overall repulsive interaction, slightly improves the level of agreement. This measurement allows for the first time an estimation of the $68$\% confidence level interval for the isospin $\mathrm{I}=0$ inverse scattering length of the $\mathrm{N\overline{D}}$ state $f_{0,~\mathrm{I}=0}^{-1}\in[-0.4, 0.9]$, assuming negligible interaction for the isospin $\mathrm{I}=1$ channel.

Abstract: The first experimental information on the strong interaction between $\Lambda$ and $\Xi^-$ strange baryons is presented in this Letter. The correlation function of $\Lambda$--$\Xi^-$ and $\overline{\Lambda}$--$\overline{\Xi}^{+}$ pairs produced in high-multiplicity proton--proton (pp) collisions at $\sqrt{s}=13$ TeV at the LHC is measured as a function of the relative momentum of the pair. The femtoscopy method is used to calculate the correlation function, which is then compared with theoretical expectations obtained using a meson exchange model, chiral effective field theory, and Lattice QCD calculations close to the physical point. Data support predictions of small scattering parameters while discarding versions with large ones, thus suggesting a weak $\Lambda$--$\Xi^{-}$ interaction. The limited statistical significance of the data does not yet allow one to constrain the effects of coupled channels like $\Sigma$--$\Xi$ and N--$\Omega$.

Abstract: Two-particle correlations are presented for $\mathrm{K^{0}_{S}}$, $\Lambda$, and $\overline{\Lambda}$ strange hadrons as a function of relative momentum in lead-lead collisions at $\sqrt{s_{_{\mathrm{NN}}}} = 5.02$ TeV. The dataset corresponds to an integrated luminosity of 0.607 $\mathrm{nb}^{-1}$ and was collected using the CMS detector at the CERN LHC. Such correlations are sensitive to quantum statistics and to final-state interactions between the particles. The source size extracted from the $\mathrm{K^{0}_{S}K^{0}_{S}}$ correlations is found to decrease from 4 to 1 fm in going from central to peripheral collisions. Strong interaction scattering parameters (i.e., scattering length and effective range) are determined from the $\Lambda\mathrm{K^{0}_{S}}$ and $\Lambda\Lambda$ (including their charge conjugates) correlations using the Lednicky--Lyuboshits model and are compared to theoretical and other experimental results.

Abstract: The dependence of the ratio between the $\mathrm{B}_\mathrm{s}$ and $\mathrm{B}^{+}$ hadron production fractions, $f_{s}/f_{u}$, on the transverse momentum ($p_T$) and rapidity of the $\mathrm{B}$ meson is studied using the decay channels $\mathrm{B}_\mathrm{s}\rightarrow\mathrm{J/\psi} \mathrm{\phi}$ and $\mathrm{B}^{+}\rightarrow \mathrm{J/\psi} \mathrm{K}^{+}$. The analysis uses a data sample of proton-proton collisions at a center-of-mass energy of 13TeV, collected by the CMS experiment in 2018 and corresponding to an integrated luminosity of 61.6 $\mathrm{fb}^{-1}$. The $f_{s}/f_{u}$ ratio is observed to depend on the $\mathrm{B}$ $p_T$, and to be consistent with becoming asymptotically constant at large $p_T$. No rapidity dependence is observed. The ratio of the $\mathrm{B}^{0}$ to $\mathrm{B}^{+}$ hadron production fractions $f_{d}/f_{u}$, measured using the $\mathrm{B}^{0} \rightarrow \mathrm{J/\psi} \mathrm{K}^{*0}$ decay channel, is found to be consistent with unity and independent of $p_T$ and rapidity.

Abstract: Two-particle Bose-Einstein momentum correlation functions for charged-hadron pairs in lead-lead collisions at a center-of-mass energy per nucleon pair of $\sqrt{s_{_{\mathrm{NN}}}} = 5.02$ TeV are studied. The data sample, containing $4.27\times 10^{9}$ events corresponding to an integrated luminosity of 0.607 $\mathrm{nb}^{-1}$, was collected by the CMS experiment in 2018. The experimental results are discussed in terms of a Levy-type source distribution. The parameters of this distribution are extracted as functions of particle pair average transverse mass and collision centrality. These parameters include the correlation strength parameter, the Levy index or shape parameter ($\alpha$), and the Levy scale parameter ($R$). The source shape, characterized by $\alpha$, is found to be neither Cauchy nor Gaussian, implying the need for a full Levy analysis. Similarly to what was previously found for systems characterized by Gaussian source radii, a hydrodynamical scaling is also observed for the Levy $R$ parameter.

Abstract: A search for supersymmetry is presented in events with a single charged lepton, electron or muon, and multiple hadronic jets. The data correspond to an integrated luminosity of 138 $\textrm{fb}^{-1}$ of proton-proton collisions at a center-of-mass energy of 13 $\textrm{TeV}$, recorded by the CMS experiment at the CERN LHC. The search targets gluino pair production, where the gluinos decay into final states with the lightest supersymmetric particle (LSP) and either a top quark-antiquark ($\textrm{t}\bar{\textrm{t}}$) pair, or a light-flavor quark-antiquark ($\textrm{q}\bar{\textrm{q}}$) pair and a virtual or on-shell $\textrm{W}$ boson. The main backgrounds, $\textrm{t}\bar{\textrm{t}}$ pair and $\textrm{W}$+jets production, are suppressed by requirements on the azimuthal angle between the momenta of the lepton and of its reconstructed parent $\textrm{W}$ boson candidate, and by top quark and $\textrm{W}$ boson identification based on a machine-learning technique. The number of observed events is consistent with the expectations from standard model processes. Limits are evaluated on supersymmetric particle masses in the context of two simplified models of gluino pair production. Exclusions for gluino masses reach up to 2120 (2050) $\textrm{GeV}$ at 95% confidence level for a model with gluino decay to a $\textrm{t}\bar{\textrm{t}}$ pair (a $\textrm{q}\bar{\textrm{q}}$ pair and a $\textrm{W}$ boson) and the LSP. For the same models, limits on the mass of the LSP reach up to 1250 (1070) $\textrm{GeV}$.

Abstract: A measurement is presented for the electroweak production of a W boson, a photon(γ), and two jets (j) in proton-proton collisions. The leptonic decay of the W boson is selected by requiring one identified electron or muon and large missing transverse momentum. The two jets are required to have large invariant dijet mass and large separation in pseudorapidity. The measurement is performed with the data collected by the CMS detector at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of $138 fb^{−1}$. The cross section for the electroweak Wγjj production in a fiducial region is $23.5^{+4.9}_{−4.7} fb$, while the total cross section for Wγjj production in the same fiducial region is 113 ± 13 fb. Differential cross sections are also measured with the distributions unfolded to the parton level. Constraints are placed on anomalous quartic gauge couplings (aQGC) in terms of dimension-8 effective field theory operators and found to be the most stringent limits to date on the aQGC parameters $f_{M,2–5}/Λ^4$ and $f_{T,6–7}/Λ^4$. All results are in agreement with the standard model expectations.

Abstract: A generic search is presented for the associated production of a Z boson or a photon with an additional unspecified massive particle X,${\rm pp}\rightarrow {\rm pp} +{\rm Z}/\gamma+{\rm X}$, in proton-tagged events from proton-proton collisions at $\sqrt{s}=13\TeV$, recorded in 2017 with the CMS detector and the CMS-TOTEM precision proton spectrometer. The missing mass spectrum is analysed in the 600--1600 GeV range and a fit is performed to search for possible deviations from the background expectation. No significant excess in data with respect to the background predictions has been observed. Model-independent upper limits on the visible production cross section of ${\rm pp}\rightarrow {\rm pp} +{\rm Z}/\gamma+{\rm X}$ are set.

Abstract: A search for long-lived particles decaying in the outer regions of the CMS silicon tracker or in the calorimeters is presented. The search is based on a data sample of proton-proton collisions at $\sqrt{s} = 13$ TeV recorded with the CMS detector at the LHC in 2016-2018, corresponding to an integrated luminosity of 138 $\text{fb}^{-1}$. A novel technique, using trackless and out-of-time jet information combined in a deep neural network discriminator, is employed to identify decays of long-lived particles. The results are interpreted in a simplified model of chargino-neutralino production, where the neutralino is the next-to-lightest supersymmetric particle, is long-lived, and decays to a gravitino and either a Higgs or $Z$ boson.This search is most sensitive to neutralino proper decay lengths of approximately 0.5 m, for which masses up to 1.18 TeV are excluded at 95% confidence level. The current search is the best result to date in the mass range from the kinematic limit imposed by the Higgs mass up to 1.8 TeV.

Abstract: The production of non-prompt $\rm D^0$ mesons from beauty-hadron decays was measured at midrapidity ($|y| < 0.5$) in Pb-Pb collisions at a nucleon-nucleon center-of-mass energy of $\sqrt{s_{\text{NN}}}=5.02$ TeV with the ALICE experiment at the LHC. Their nuclear modification factor ($R_{\rm AA}$), measured for the first time down to $p_{\rm T}$ = 1 GeV/$c$  in the 0-10% and 30-50% centrality classes, indicates a significant suppression, up to a factor of about three, for $p_{\rm T}$ > 5 GeV/$c$ in the 0-10% central Pb--Pb collisions.The data are described by models that include both collisional and radiative processes in the calculation of beauty-quark energy loss in the quark--gluon plasma, and quark recombination in addition to fragmentation as a hadronization mechanism. The ratio of the non-prompt to prompt $\rm D^0$-meson $R_{\rm AA}$ is larger than unity for $p_{\rm T}$ > 4 GeV/$c$ in the 0-10% central Pb-Pb collisions, as predicted by models in which beauty quarks lose less energy than charm quarks in the quark-gluon plasma because of their larger mass.

Abstract: A search is performed for exclusive high-mass $\gamma\gamma \to WW$ and $\gamma\gamma \to ZZ$ production in proton-proton collisions using intact forward protons reconstructed in near-beam detectors, with both weak bosons decaying into boosted and merged jets. The analysis is based on a sample of proton-proton collisions collected by the CMS and TOTEM experiments at $\sqrt{s}=13$~TeV, corresponding to an integrated luminosity of 100~$\mathrm{fb}^{-1}$. No excess above the standard model background prediction is observed, and upper limits are set on the $pp \to pWWp$ and $pp \to pZZp$ cross sections in a fiducial region defined by the diboson invariant mass $m(VV)>1$~TeV (with $V =W,Z$) and proton fractional momentum loss $0.04 < \xi < 0.20$. The results are interpreted as new limits on dimension-6 and dimension-8 anomalous quartic gauge couplings.

Abstract: The production yields of non-prompt $\mathrm{D}_{s}^{+}$ mesons, namely $\mathrm{D}_{s}^{+}$ mesons from beauty-hadron decays, were measured for the first time as a function of the transverse momentum ($p_{T}$) at midrapidity ($|y|<0.5$) in central and semi-central Pb--Pb collisions at a centre-of-mass energy per nucleon pair $\sqrt{s_{NN}}=5.02~$TeV with the ALICE experiment at the LHC.The $\mathrm{D}_{s}^{\pm}$ mesons were reconstructed from the hadronic decay channel $\rm D_s^{+}\to \phi\pi^+$, with $\rm \phi\to K^-K^+$, in the $4

Abstract: The observation of the production of four top quarks in proton-proton collisions is reported, based on a data sample collected by the CMS experiment at a center-of-mass energy of 13 TeV in 2016-2018 at the CERN LHC and corresponding to an integrated luminosity of 138 $\text{fb}^{-1}$.Events with two same-sign, three, or four charged leptons (electrons and muons) and additional jets are analyzed.Compared to previous results in these channels, updated identification techniques for charged leptons and jets originating from the hadronization of $b$ quarks, as well as a revised multivariate analysis strategy to distinguish the signal process from the main backgrounds, lead to an improved expected signal significance of 4.9 standard deviations above the background-only hypothesis.Four top quark production is observed with a significance of 5.6 standard deviations, and its cross section is measured to be $17.6^{+3.7}_{-3.5} \text{(stat)} ^{+2.3}_{-1.9} \text{(syst)}$, in agreement with the available theoretical predictions.

Abstract: A search for the lepton-flavor violating decay of the Higgs boson and potential additional Higgs bosons with a mass from 110-160 $\mathrm{GeV}$ to an $e^{\pm}\mu^{\mp}$ pair is presented. The search is performed with a proton-proton collision data set at a center-of-mass energy of 13 $\mathrm{TeV}$ collected by the CMS experiment at the LHC, corresponding to an integrated luminosity of 138 $\mathrm{fb}^{-1}$. No excess is observed for the Higgs boson. The observed (expected) upper limit on the $e^{\pm}\mu^{\mp}$ branching fraction for it is determined to be $4.4\ (4.7)\times10^{-5}$ at 95% confidence level, the most stringent limit set thus far from direct searches. The largest excess of events over the expected background in the full mass range of the search is observed at an $e^{\pm}\mu^{\mp}$ invariant mass of approximately 146 $\mathrm{GeV}$ with a local (global) significance of 3.8 (2.8) standard deviations.

Abstract: A search for resonances in the γ+jet final state has been performed using proton- proton collision data collected at √s = 13 TeV by the CMS experiment at the LHC. The total data analyzed correspond to an integrated luminosity of 138 fb−1. Mod- els of excited quarks, including heavy-flavor quarks, and quantum black holes are considered. The invariant mass spectrum of the γ+jet system is examined for the presence of resonances over the standard model continuum background. The data exhibit no statistically significant deviations from the expected standard model back- ground. Exclusion limits at 95% confidence level on the resonance mass and other parameters are set. Excited (heavy-flavor) quarks are excluded up to a mass of 6.0 (2.2) TeV. Quantum black hole production is excluded for masses up to 7.5 (5.2) TeV in the Arkani-Hamed–Dimopoulos–Dvali (Randall–Sundrum) models.

Abstract: Measurements of the inclusive and differential fiducial cross sections for the Higgs boson production in the $\mathrm{H}\rightarrow{\rm Z}{\rm Z}\rightarrow4\ell$ ($\ell={\rm e},\mu$) decay channel are presented.The results are obtained from the analysis of proton-proton collision data recorded by the CMS experiment at the CERN LHC at a center-of-mass energy of $13~\mathrm{TeV}$, corresponding to an integrated luminosity of $138~\mathrm{fb}^{-1}$.The measured inclusive fiducial cross section is $2.73\pm0.26~\mathrm{fb}$, in agreement with the standard model expectation of $2.86\pm0.15~\mathrm{fb}$.Differential cross sections are measured as a function of several kinematic observables sensitive to the Higgs boson production and decay to four leptons.A set of double-differential measurements is also performed, yielding a comprehensive characterization of the four leptons final state.Constraints on the Higgs boson trilinear coupling and on the bottom and charm quark coupling modifiers are derived from its transverse momentum distribution.All results are consistent with theoretical predictions from the standard model.

Abstract: A search for prompt low-mass dimuon resonances is performed using the 13 TeV proton-proton collision data collected by the Compact Muon Solenoid (CMS) detector during the 2017--2018 operation of the CERN's Large Hadron Collider and corresponding to an integrated luminosity of 96.6 fb^-1. The search exploits a dedicated scouting trigger stream allowing CMS to record events with two muons with transverse momenta as low as 3 GeV by trading off recording the full event information. The search is performed by looking for narrow resonance peaks in the dimuon mass continuum in the ranges from 1.1--2.6 and from 4.2--7.9 GeV.No significant excess of events above the expectation from the standard model background is observed. Model-independent limits on production rates of dimuon resonances within the experimental fiducial acceptance are set. Limits on parameters for two specific models, a dark photon model and a two Higgs doublet model with an extra scalar, are also set.

Abstract:
Two-particle correlations with K$^{0}_\mathrm{S}$, $\Lambda/\overline{\Lambda}$, and charged hadrons as trigger particles in the transverse momentum range $8 < p_\mathrm{T,trig}<16$ GeV/$c$, and associated charged particles within $1 < p_\mathrm{T,assoc}<8$ GeV/$c$, are studied at mid-rapidity in pp and central Pb$-$Pb collisions at a centre-of-mass energy per nucleon--nucleon collision $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV with the ALICE detector at the LHC.
After subtracting the contributions of the flow background, the per-trigger yields are extracted on both the near and away sides, and the ratio in Pb$-$Pb collisions with respect to pp collisions ($I_{\mathrm{AA}}$) is computed. The per-trigger yield in Pb$-$Pb collisions on the away side is strongly suppressed to the level of $I_{\mathrm{AA}}$
$\approx 0.6$ for $p_\mathrm{T,assoc}>3$ GeV/$c$ as expected from strong in-medium energy loss, while an enhancement develops at low $p_\mathrm{T,assoc}$ on both the near and away sides, reaching $I_{\mathrm{AA}}$ $\approx 1.8$ and $2.7$ respectively. These findings are in good agreement with previous ALICE measurements from two-particle correlations triggered by neutral pions ($\pi^{0}$--h) and charged hadrons (h--h) in Pb$-$Pb collisions at $\sqrt{s_{\mathrm{NN}}}= 2.76$ TeV. Moreover, the correlations with K$^{0}_\mathrm{S}$ mesons and $\Lambda/\overline{\Lambda}$ baryons as trigger particles are compared to those of inclusive charged hadrons. The results are compared with the predictions of Monte Carlo models.

Abstract: A newly developed observable for correlations between symmetry planes, which characterize the direction of the anisotropic emission of produced particles, is measured in Pb--Pb collisions at $\sqrt{s_\text{NN}}$ = 2.76 TeV with ALICE. This so-called Gaussian Estimator allows for the first time the study of these quantities without the influence of correlations between different flow amplitudes. The centrality dependence of various correlations between two, three and four symmetry planes is presented. The ordering of magnitude between these symmetry plane correlations is discussed and the results of the Gaussian Estimator are compared with measurements of previously used estimators. The results utilizing the new estimator lead to significantly smaller correlations than reported by studies using the Scalar Product method. Furthermore, the obtained symmetry plane correlations are compared to state-of-the-art hydrodynamic model calculations for the evolution of heavy-ion collisions. While the model predictions provide a qualitative description of the data, quantitative agreement is not always observed, particularly for correlators with significant non-linear response of the medium to initial state anisotropies of the collision system. As these results provide unique and independent information, their usage in future Bayesian analysis can further constrain our knowledge on the properties of the QCD matter produced in ultrarelativistic heavy-ion collisions.

Abstract: A search for pair production of heavy Majorana neutrinos (N) from the decays of Z' bosons is performed using the CMS detector at the LHC. The data were collected in proton-proton collisions at a center-of-mass energy of $\sqrt{s}$ = 13 TeV, with an integrated luminosity of $138 fb^{-1}$. The signature for the search is two same-flavor leptons (e or $\mu$) and at least two jets. No significant excess of events beyond the expected background is observed. Upper limits at 95\% confidence level are set on the product of cross section and branching fraction for the pair production of ${N}_{l}$, as functions of ${N}_{l}$ and Z' boson masses (${m}_{N}$ and ${m}_{Z'}$, respectively) for ${m}_{Z'}$ from $0.4$ to 4.4 TeV and ${m}_{N}$ from 0.1 TeV to ${m}_{Z'}/2$. In the theoretical framework of a left-right symmetric model, exclusion bounds on the ${m}_{N}$-${m}_{Z'}$ plane are presented in both the electron and muon channels. The observed upper limit on ${m}_{Z'}$ reaches up to 4.42 TeV.

Abstract: A search for high-mass dimuon resonance production in association with one or more $\mathrm{b}$ quark jets is presented. The study uses proton-proton collision data collected with the CMS detector at the LHC corresponding to an integrated luminosity of $138~\mathrm{fb}^{-1}$ at a center-of-mass energy of $13~\mathrm{TeV}$. Model-independent limits are derived on the number of signal events with exactly one or more than one $\mathrm{b}$ quark jet. Results are also interpreted in a lepton-flavor-universal model with $\mathrm{Z'}$ boson couplings to a $\mathrm{bb}$ quark pair ($g_{\mathrm{b}}$), an $\mathrm{sb}$ quark pair ($g_{\mathrm{b}}\delta_{\mathrm{bs}}$), and any same-flavor charged lepton ($g_{\ell}$) or neutrino pair ($g_{\nu}$), with $|g_{\nu}|=|g_{\ell}|$. For a $\mathrm{Z'}$ boson with a mass $m_{\mathrm{Z'}}=350~\mathrm{GeV}$ ($2~\mathrm{TeV}$) and $|\delta_{\mathrm{bs}}| < 0.25$, the majority of the parameter space with $0.0057 < |g_{\ell}| < 0.35$ ($0.25 < |g_{\ell}| < 0.43$) and $0.0079 < |g_{\mathrm{b}}| < 0.46$ ($0.34 < |g_{\mathrm{b}}| < 0.57$) is excluded at $95\%$ confidence level. Finally, constraints are set on a $\mathrm{Z'}$ model with parameters consistent with low-energy $\mathrm{b} \to \mathrm{s}\ell\ell$ measurements. In this scenario, most of the allowed parameter space is excluded for a $\mathrm{Z'}$ boson with $350

Abstract: CERN-LHC. A study of multiplicity and pseudorapidity distributions of inclusive photons measured in pp and p-Pb collisions at a center-of-mass energy per nucleon-nucleon collision of $\sqrt{s_\mathrm{NN}} = 5.02~\mathrm{TeV}$ using the ALICE detector in the forward pseudorapidity region $2.3<\eta_{\rm lab}<3.9$ is presented. Measurements in p-Pb collisions are reported for two beam configurations in which the directions of the proton and lead ion beam were reversed. The pseudorapidity distributions in p-Pb collisions are obtained for seven centrality classes which are defined based on different event activity estimators, i.e., the charged-particle multiplicity measured at midrapidity as well as the energy deposited in a calorimeter at beam rapidity. The inclusive photon multiplicity distributions for both pp and p-Pb collisions are described by double negative binomial distributions. The pseudorapidity distributions of inclusive photons are compared to those of charged particles at midrapidity in pp collisions and for different centrality classes in p-Pb collisions. The results are compared to predictions from various Monte Carlo event generators. None of the generators considered in this paper reproduces the inclusive photon multiplicity distributions in the reported multiplicity range. The pseudorapidity distributions are, however, better described by the same generators.

Abstract: The strange quark content of the proton is probed through the measurement of the production cross section for a W boson and a charm (c) quark in proton-proton collisions at a center-of-mass energy of 13 TeV. The analysis uses a data sample corresponding to a total integrated luminosity of 138 fb$^{-1}$ collected with the CMS detector at the LHC. The W bosons are identified through their leptonic decays to an electron or a muon, and a neutrino. Charm jets are taggedusing the presence of a muon or a secondary vertex inside the jet.The W+c production cross section and the cross section ratio $R_c^{\pm} = \sigma({\rm W^+ + \bar{c}}) / \sigma({\rm W^- + c}) $ are measured inclusively and differentially as functions of the transverse momentum and the pseudorapidity of the lepton originating from the W boson decay.The precision of the measurements has been improved with respect to previous studies, reaching 1% in $R_c^{\pm}$. The measurements are compared with theoretical predictions up to next-to-next-to-leading order in perturbative quantum chromodynamics.

Abstract: A search is presented for a third-generation leptoquark (LQ) coupled exclusively to a $\tau$ lepton and a b quark. The search is based on proton-proton collision data at a center-of-mass energy of $\sqrt{s}=13\,\mathrm{TeV}$ recorded with the CMS detector, corresponding to an integrated luminosity of $138\,\mathrm{fb}^{-1}$. Events with $\tau$ leptons and a varying number of jets originating from b quarks are considered, targeting the single and pair production of LQs, as well as nonresonant $t$-channel LQ exchange. An excess is observed in the data with respect to the background expectation in the combined analysis of all search regions. For a benchmark LQ mass of 2 TeV and a coupling strength of 2.5, the excess reaches local significances of up to 2.8 standard deviations. Upper limits at the $95\%$ confidence level are placed on the LQ production cross section in the LQ mass range 0.5-2.3 TeV, and up to 3 TeV for $t$-channel LQ exchange. Leptoquarks are excluded below masses of 1.22-1.88 TeV for different LQ models and varying coupling strengths up to 2.5. Considering only LQ exchange in the $t$ channel, constraints are placed on LQs with masses and coupling strengths of up to 3 TeV and 3.5, respectively.

Abstract: A search is presented for high-mass exclusive diphoton production via photon-photon fusion in proton-proton collisions at $\sqrt{s} = 13 TeV$ in events where both protons survive the interaction. The analysis utilizes data corresponding to an integrated luminosity of 103 $fb^{-1}$ collected in 2016--2018 with the central CMS detector and the CMS and TOTEM precision proton spectrometer (PPS). Events that have two photons with high transverse momenta ($p_T^{\gamma} > 100 GeV$), back-to-back in azimuth, and with a large diphoton invariant mass ($m_{\gamma\gamma} > 350 GeV$) are selected. To remove the dominant inclusive diphoton backgrounds, the kinematic properties of the protons detected in PPS are required to match those of the central diphoton system. Only events having opposite-side forward protons detected with a fractional momentum loss between 0.035 and 0.15 (0.18) for the detectors on the negative (positive) side of CMS are considered. One exclusive diphoton candidate is observed for an expected background of 1.1 events. Limits at 95\% confidence level are derived for the four-photon anomalous coupling parameters $\abs{\zeta_1} < 0.073 TeV^{-4}$ and $\abs{\zeta_2} < 0.15 TeV^{-4}$, using an effective field theory. Additionally, upper limits are placed on the production of axion-like particles with coupling strength to photons $f^{-1}$ that varies from $0.03 TeV^{-1}$ to $1 TeV^{-1}$ over the mass range from 500 to 2000 GeV.

Abstract: The first evidence for the Higgs boson decay to a $Z$ boson and a photon is presented, with a statistical significance of 3.4 standard deviations. The result is derived from a combined analysis of the searches performed by the ATLAS and CMS Collaborations with proton-proton collision data sets collected at the CERN Large Hadron Collider (LHC) from 2015 to 2018. These correspond to integrated luminosities of around 140 fb$^{-1}$ for each experiment, at a center-of-mass energy of 13 TeV. The measured signal yield is 2.2$\pm$0.7 times the Standard Model prediction, and agrees with the theoretical expectation within 1.9 standard deviations.

Abstract: CERN-LHC. ALICE. Multiplicity ($N_{\mathrm{ch}}$) distributions and transverse momentum ($p_{\mathrm{T}}$) spectra of inclusive primary charged particles in the kinematic range of $|\eta| < 0.8$ and $0.15\ \mathrm{GeV}/c < p_{\mathrm{T}} < 10\ \mathrm{GeV}/c$ are reported for pp, p-Pb, Xe-Xe and Pb-Pb collisions at centre-of-mass energies per nucleon pair ranging from $\sqrt{s_\mathrm{NN}} = 2.76\ \mathrm{TeV}$ up to $13\ \mathrm{TeV}$. The multiplicity distributions are also shown in their KNO-scaled form. The correlation between the transverse momentum of primary charged particles and the charged-particle multiplicity of the corresponding collision is reported in fine intervals. In addition, the mean $ \langle p_{\mathrm{T}} \rangle $ and standard deviation $ \sigma(p_{\mathrm{T}}) $ derived from these multiplicity dependent $p_\mathrm{T}$ spectra are shown as a function of $N_{\mathrm{ch}}$. The relative standard deviation $ \sigma(p_{\mathrm{T}}) / \langle p_{\mathrm{T}} \rangle $ of the spectra is reported as well. All observables are also presented as a function of the reltaive multiplicity $ N_{\mathrm{ch}}\ / \langle N_{\mathrm{ch}} \rangle $. Note that $ \langle N_{\mathrm{ch}} \rangle $ is calculated for the whole multiplicity range extending beyond the $N_{\mathrm{ch}}$ values reported for the multiplicity-differential observables. Also the transverse momentum spectra integrated over this full range of multiplicities are presented. The mean and standard deviation derived from these multiplicity-integrated $p_\mathrm{T}$ spectra are used to normalize the corresponding multiplicity-dependent values which are then reported as a function of $ N_{\mathrm{ch}}\ / \langle N_{\mathrm{ch}} \rangle $.

Abstract: A combination of fifteen top quark mass measurements performed by the ATSLAS and CMS experiments at the LHC is presented. The data sets used correspond to an integrated luminosity of up to 5 and 20 fb$^{-1}$ of proton-proton collisions at center-of-mass energies of 7 and 8 TeV, respectively. The combination includes measurements in top-quark pair events that exploit both the semi-leptonic and hadronic decays of the top quark, and a measurement using events enriched in single top quark production via the electroweak-channel. The combination yields $m_t=172.52\pm 0.14 (\text{stat.}) \pm 0.30 (\text{syst.})$ GeV, with a total uncertainty of 0.33 GeV.

Abstract: A search for narrow hadronic resonances decaying to three resolved jets is presented. The search uses proton-proton collision data corresponding to an integrated luminosity of 138\fbinv, at a center-of-mass energy of 13 TeV, collected with the CMS detector at the CERN LHC. The three-jet invariant mass spectrum is scrutinized for localized excesses compatible with new resonances with masses in the range of $1.75$--$9.00\,\text{TeV}$. The background from standard model processes is estimated by fitting the three-jet invariant mass spectrum with empirical functions, following techniques commonly used in dijet resonance searches. No significant deviations from the background expectations are observed. The results are interpreted in the context of several models predicting three-jet resonances, including a new right-handed boson $\mathrm{Z}_{\mathrm{R}}$ decaying to three gluons, a Kaluza--Klein gluon decaying via an intermediate radion to three gluons, and an excited quark decaying via a vector boson to three quarks.

Abstract: A search for electroweak production of a single vector-like quark tprime in association with a bottom quark (b) and decaying fully hadronically is presented. This search uses proton-proton collision data at $\sqrt{s} = 13\TeV$ collected by the CMS experiment at the CERN LHC during 2016-2018, corresponding to an integrated luminosity of 138\fbinv. The tprime have charge 2/3 and can decay to a top quark (t) and a Higgs or Z boson. Event kinematics and the presence of jets containing b hadrons are used to reconstruct the hadronic decays of the t and Higgs or Z boson. No discrepancy from the standard model prediction is observed in the data. For \tprime masses from 600 to 1200~GeV, the 95% confidence level upper limits on the production cross section of a tprime produced in association with a b and decaying via a t and a Higgs or Z boson range from 1260 to 68 fb.

Abstract: A search for W' bosons decaying to a top and a bottom quark in final states including electrons or muons is performed with the CMS detector at the LHC. The analyzed data correspond to an integrated luminosity of $138~\mathrm{fb}^{-1}$ of proton-proton collisions at a center-of-mass energy of $13~\mathrm{TeV}$. In general, good agreement with the standard model expectation is observed and no evidence for the existence of the W' boson is found over the mass range examined. The largest observed excess is found for a W' boson mass ($m_{\mathrm{W'}}$) hypothesis of $3.8~\mathrm{TeV}$ with a relative decay width of $1\%$, with a local (global) significance of $2.6$ $(2.0)$ standard deviations. Upper limits on the production cross sections of W' bosons decaying to a top and a bottom quark are set. Left- and right-handed W' bosons with $m_{\mathrm{W'}}$ below $3.9$ and $4.3~\mathrm{TeV}$, respectively, are excluded at the $95\%$ confidence level, under the assumption that the new particle has a narrow decay width. Limits are also set for relative decay widths up to $30\%$. These are the most stringent limits to date on W' bosons decaying to a top and a bottom quark.

Abstract: The polarization of $\tau^{-}$ leptons is measured using leptonic and hadronic $\tau^{-}$ lepton decays in $Z\rightarrow \tau^{+}\tau^{-}$ events in proton-proton collisions at $\sqrt{s}=13\,\mathrm{TeV}$ recorded by CMS at the CERN LHC with an integrated luminosity of $36.3\,\mathrm{fb}^{-1}$.The measured $\tau^{-}$ polarization at the $\mathrm{Z}$ boson mass pole is $\mathcal{P}_{\tau}(\mathrm{Z})=-0.144\pm0.006\,(\text{stat})\,\pm0.014\,(\text{syst})=-0.144\pm0.015$,in good agreement with the measurement of the $\tau$ lepton asymmetry parameter of $A_{\tau}=0.1439\pm0.0043=-\mathcal{P}_{\tau}(\mathrm{Z})$ at LEP.The $\tau$ polarization depends on the ratio of the vector to axial-vector couplings of the $\tau$ leptons in the neutral current expression, and thus on the effective weak mixing angle $ \sin^{2}\theta_{\mathrm{W}}^{\mathrm{eff}}$, independently of the $\mathrm{Z}$ boson production mechanism.The obtained value $ \sin^{2}\theta_{\mathrm{W}}^{\mathrm{eff}}=0.2319\pm0.0008\,(\text{stat})\pm0.0018\,(\text{syst})=0.2319\pm0.0019$is in good agreement with measurements at $\mathrm{e^{+}e^{-}}$ colliders.

The pseudorapidity density of charged particles with minimum transverse momentum ($p_{T}$) thresholds of 0.15, 0.5, 1, and 2 GeV$/c$ was measured in pp collisions at centre-of-mass energies of $\sqrt{s}$ = 5.02 and 13 TeV with the ALICE detector. The study is carried out for inelastic collisions with at least one primary charged particle having a pseudorapidity ($\eta$) within $\pm0.8$ and $p_{T}$ larger than the corresponding threshold. The measurements were also performed for inelastic and non-single-diffractive events as well as for inelastic events with at least one charged particle having $|\eta|<1$ in pp collisions at $\sqrt{s}$ = 5.02 TeV for the first time at the LHC. The measurements are compared to the PYTHIA 6, PYTHIA 8, and EPOS-LHC models. In general, the models describe the pseudorapidity dependence of particle production well, however, discrepancies are observed for event classes including diffractive events and for the highest transverse momentum threshold ($p_{T}>2 {\rm\ GeV}/c$), highlighting the importance of such measurements for tuning event generators. The new measurements agree within uncertainties with results from the ATLAS and CMS experiments.

Abstract: The observation of $WW\gamma$ production in proton-proton collisions at a center-of-mass energy of 13\TeV with an integrated luminosity of 138\fbinv is presented. The observed (expected) significance is 5.6 (4.7) standard deviations. Events are selected by requiring exactly two leptons (one electron and one muon) of opposite charge, moderate missing transverse momentum, and a photon. The measured fiducial cross section for $WW\gamma$ is $ 6.0 \pm 0.8 \text{(stat)} \pm 0.7 \text{(syst)} \pm 0.6 \text{(modeling)} fb$, in agreement with the next-to-leading order quantum chromodynamics prediction. The analysis is extended with a search for the associated production of the Higgs boson and a photon, which is generated by a coupling of the Higgs boson to light quarks. The result is used to constrain the Higgs boson couplings to light quarks.

Abstract: We present the first comprehensive tests of the universality of the light leptons in the angular distributions of semileptonic $B^0$-meson decays to charged spin-1 charmed mesons. We measure five angular-asymmetry observables as functions of the decay recoil that are sensitive to lepton-universality-violating contributions. We use events where one neutral $B$ is fully reconstructed in $\Upsilon\left(4S\right)\to{}B\overline{B}$ decays in data corresponding to $189~\mathrm{fb}^{-1}$ integrated luminosity from electron-positron collisions collected with the Belle II detector. We find no significant deviation from the standard model expectations.

Abstract: The interactions of kaons (K) and antikaons ($\mathrm{\overline{K}}$) with few nucleons (N) were studied so far using kaonic atom data and measurements of kaon production and interaction yields in nuclei. Some details of the three-body KNN and $\mathrm{\overline{K}}$NN dynamics are still not well understood, mainly due to the overlap with multi-nucleon interactions in nuclei. An alternative method to probe the dynamics of three-body systems with kaons is to study the final state interaction within triplet of particles emitted in pp collisions at the Large Hadron Collider, which are free from effects due to the presence of bound nucleons. This Letter reports the first femtoscopic study of p-p-K$^+$ and p-p-K$^-$ correlations measured in high-multiplicity pp collisions at $\sqrt{s}$ = 13 TeV by the ALICE Collaboration. The analysis shows that the measured p-p-K$^+$ and p-p-K$^-$ correlation functions can be interpreted in terms of pairwise interactions in the triplets, indicating that the dynamics of such systems is dominated by the two-body interactions without significant contributions from three-body effects or bound states.
