Abstract: CERN-LHC. The measurements of differential cross sections for the production of two Z bosons in association with jets in proton-proton collisions at 13 TeV an 8 TeV are reported. The analysis is based on data samples collected at the LHC with the CMS detector, corresponding to integrated luminosities of 19.7 and 35.9 fb-1 at 8 and 13 TeV, respectively. The measurements are performed in the leptonic decay modes $\textrm{p} \textrm{p} \to \textrm{ZZ}\to \ell\ell\ell^{\prime}\ell^{\prime}$, where where $\ell,\ell^{\prime} = e, \mu$. The differential cross sections as a function of the jet multiplicity, the transverse momentum $p_T$, and pseudorapidity of the $p_T$-leading and subleading jets are presented. In addition, the differential cross sections as a function of variables sensitive to the vector boson scattering, such as the invariant mass of the two $p_T$-leading jets and their pseudorapidity separation, are reported. The fiducial region for the 13 TeV analysis is defined as: leading lepton $p_T$ > 20 GeV, subleading lepton $p_T$ > 10 GeV, lepton $p_T$ > 5 GeV, psudorapidity of electrons and muons |eta| < 2.5, invariant mass of any opposite-sign same-flavor lepton pair $\textrm{m}_{\ell \ell} > 4$ GeV, invariant mass of the Z boson $60 < \textrm{m}_{\textrm{Z1}},\textrm{m}_{\textrm{Z2}} < 120$ GeV. The fiducial region for the 8 TeV analysis is defined as: leading lepton $p_T$ > 20 GeV, subleading lepton $p_T$ > 10 GeV, muon $p_T$ > 5 GeV, electron $p_T$ > 7 GeV, psudorapidity of electrons |eta| < 2.5, psudorapidity of muons |eta| < 2.4, invariant mass of any opposite-sign same-flavor lepton pair $\textrm{m}_{\ell \ell} > 4$ GeV, invariant mass of the Z boson $60 < \textrm{m}_{\textrm{Z1}},\textrm{m}_{\textrm{Z2}} < 120$ GeV. The generator-level lepton momenta are corrected by adding the momenta of generator-level photons within $\Delta \textrm{R} \left(\ell,\gamma\right) < 0.1$

Abstract:
CERN-LHC. A search for the production of events containing three W bosons predicted by the standard model is reported. The search is based on a data sample of proton-proton collisions at a center-of-mass energy of 13 TeV recorded by the CMS experiment at the CERN LHC and corresponding to a total integrated luminosity of 35.9 $\mathrm{fb}^{−1}$. The search is performed in final states with three leptons (electrons or muons), or with two same-charge leptons plus two jets. The observed (expected) significance of the signal for $\mathrm{W}^{\pm}\mathrm{W}^{\pm}\mathrm{W}^{\mp}$ production is 0.60 (1.78) standard deviations, and the ratio of the measured signal yield to that expected from the standard model is $0.34^{+0.62}_{−0.34}.

Abstract: CERN-LHC. The transverse structure of jets was studied via jet fragmentation transverse momentum ($j_{\rm T}$) distributions, obtained using two-particle correlations in proton-proton and proton-lead collisions, measured with the ALICE experiment at the LHC. The highest transverse momentum particle in each event is used as the trigger particle and the region $3 < p_{\rm T} < 15$ ~GeV/$c$ is explored in this study.

Abstract:
CERN-LHC. The ALICE Collaboration has measured the energy dependence of exclusive photoproduction of J/PSI vector mesons off proton targets in ultra-peripheral proton-lead collisions at a centre-of-mass energy per nucleon pair sqrt(sNN) = 5.02$ TeV. The E+E-$ and MU+MU-$ decay channels are used to measure the cross section as a function of the rapidity of the J
SI in the range $-2.5 < y < 2.7$, corresponding to an energy in the GAMMA-P centre-of-mass in the interval 40 < W(GAMMA P) <550$ GeV. The differential cross section as a function of rapidity is also presented along with the product of the photon energy, K, and the photon flux, DN/DK.

Abstract: We report on the first femtoscopic measurement of baryon pairs, such as p$-$p, p$-\Lambda$ and $\Lambda-\Lambda$, measured by ALICE at the Large Hadron Collider (LHC) in proton-proton collisions at $\sqrt{s} = 7$ TeV. This study demonstrates the feasibility of such measurements in pp collisions at ultrarelativistic energies. The femtoscopy method is employed to constrain the hyperon$-$nucleon and hyperon$-$hyperon interactions, which are still rather poorly understood. A new method to evaluate the influence of residual correlations induced by the decays of resonances and experimental impurities is hereby presented. The p$-$p, p$-\Lambda$ and correlation functions were fitted simultaneously with the help of a new tool developed specifically for the femtoscopy analysis in small colliding systems "Correlation Analysis Tool using the Schrödinger Equation" (CATS). Within the assumption that in pp collisions the three particle pairs originate from a common source, its radius is found to be equal to $r_0 = 1.125 \pm 0.018$ (stat) $^{+0.058} _{-0.035}$ (syst) fm. The sensitivity of the measured p$-\Lambda$ correlation is tested against different scattering parameters which are defined by the interaction among the two particles, but the statistics is not sufficient yet to discriminate among different models. The measurement of the $\Lambda-\Lambda$ correlation function constrains the phase space spanned by the effective range and scattering length of the strong interaction. Discrepancies between the measured scattering parameters and the resulting correlation functions at LHC and RHIC energies are discussed in the context of various models.

Abstract: A search for direct top squark pair production resulting in events with either a same-flavour opposite-sign dilepton pair with invariant mass compatible with a $Z$ boson or a pair of jets compatible with a Standard Model (SM) Higgs boson ($h$) is presented. Requirements on additional leptons, jets, jets identified as originating from b-quarks, and missing transverse momentum are imposed to target the other decay products of the top squark pair. The analysis is performed using proton-proton collision data at sqrt{s} = 13 TeV collected with the ATLAS detector at the LHC in 2015-2016, corresponding to an integrated luminosity of 36.1 fb$^{−1}$. No excess is observed in the data with respect to the expected SM predictions. The results are interpreted in two sets of models. In the first set, direct production of pairs of lighter top squarks ($\tilde{t}_1$) with long decay chains involving $Z$ or Higgs bosons is considered. The second set includes direct pair production of the heavier top squark pairs ($\tilde{t}_2$) decaying via $\tilde{t}_2 \rightarrow Z \tilde{t}_1$ or $\tilde{t}_2 \rightarrow h \tilde{t}_1$. The results exclude at 95% confidence level $\tilde{t}_2$ and $\tilde{t}_1$ masses up to about 800 GeV, extending the exclusion region of supersymmetric parameter space covered by previous LHC searches.

Abstract: CERN-LHC. The measurements of the production of prompt $\rm{D}^{0}$, $\rm{D}^{+}$, $\rm D^{*+}$ and $\rm D_{s}$ mesons in proton-proton (pp) collisions at $\sqrt{s_{\rm{NN}}}$=5.02 TeV with the ALICE detector at the Large Hadron Collider (LHC) are reported. D mesons were reconstructed at mid-rapidity ($|y|<0.5$) via their hadronic decay channels $\rm{D^{0}}\rightarrow K\pi$, $\rm{D^{+}}\rightarrow K\pi\pi$, $\rm{D}^{*+}\rightarrow \rm{D}^{0}\pi\rightarrow K\pi\pi$, $\rm{D_{s}}\rightarrow\phi\pi\rightarrow K K \pi$, and their charge conjugates. The production cross sections were measured in the transverse momentum interval 0<$p_{\rm T}$<36 GeV/$c$ for $\rm{D}^{0}$, 1<$p_{\rm T}$<36 GeV/$c$ for $\rm{D}^{+}$ and $\rm D^{*+}$, and in 2<$p_{\rm T}$<24 GeV/$c$ for $\rm D_{s}$ mesons. Thanks to the higher integrated luminosity, an analysis in finer $p_{\rm T}$ bins with respect to the previous measurements at $\sqrt{s}$=7 Tev was performed, allowing for a more detailed description of the cross-section $p_{\rm T}$ shape. The measured $p_{\rm T}$-differential production cross sections are compared to the results at $\sqrt{s}$=7 TeV and to four different perturbative QCD calculations. Its rapidity dependence is also tested combining the ALICE and LHCb measurements in pp collisions at $\sqrt{s}$=5.02 TeV. This measurement will allow for a more accurate determination of the nuclear modification factor in p-Pb and Pb-Pb collisions performed at the same nucleon-nucleon centre-of-mass energy.

Abstract: The second and the third order anisotropic flow, V2 and V3, are mostly determined by the corresponding initial spatial anisotropy coefficients, epsilon2 and epsilon3, in the initial density distribution. In addition to their dependence on the same order initial anisotropy coefficient, higher order anisotropic flow, Vn (n > 3), can also have a significant contribution from lower order initial anisotropy coefficients, which leads to mode-coupling effects. In this Letter we investigate the linear and non-linear modes in higher order anisotropic flow Vn for n = 4, 5, 6 with the ALICE detector at the Large Hadron Collider. The measurements are done for particles in the pseudorapidity range eta < 0.8 and the transverse momentum range 0.2 < pT < 5.0 GeV/c as a function of collision centrality. The results are compared with theoretical calculations and provide important constraints on the nature of the initial geometry fluctuations as well as the ratio of the shear viscosity to entropy density of the produced system.

Abstract: Charged-particle spectra at midrapidity are measured in Pb--Pb collisions at the centre-of-mass energy per nucleon--nucleon pair $\snn = 5.02$ TeV and presented in centrality classes ranging from most central~(0--5\%) to most peripheral~(95--100\%) collisions. Possible medium effects are quantified using the nuclear modification factor~($\RAA$) by comparing the measured spectra with those from proton--proton collisions, scaled by the number of independent nucleon--nucleon collisions obtained from a Glauber model.

Abstract: A search for anomalous electroweak production of WW, WZ, and ZZ boson pairs in association with two jets in proton-proton collisions at $\sqrt{s}=13$ TeV at the LHC is reported. The data sample corresponds to an integrated luminosity of $35.9$ fb$^{-1}$ collected with the CMS detector. Events are selected by requiring two jets with large rapidity separation and invariant mass, one or two leptons (electrons or muons), and a W or Z boson decaying hadronically. No excess of events with respect to the standard model background predictions is observed and constraints on the structure of quartic vector boson interactions in the framework of dimension-8 effective field theory operators are reported. Stringent limits on parameters of the effective field theory operators are obtained. The observed $95\%$ confidence level limits for the S0, M0, and T0 operators are $-2.7

Abstract: A measurement of the production of prompt $\Lambda_{\rm {c}}^{+}$ baryons in Pb-Pb collisions at $\sqrt{s_{\rm {NN}}} = 5.02$ TeV with the ALICE detector at the LHC is reported. The $\Lambda_{\rm {c}}^{+}$ and $\Lambda_{\rm {c}}^{-}$ were reconstructed at midrapidity ($|y| < 0.5$) via the hadronic decay channel $\Lambda_{\rm {c}}^{+} \to {\rm {p}} {\rm {K}}^{0}_{\rm {S}}$ (and charge conjugate) in the transverse momentum and centrality intervals 6 < $p_{\rm {T}}$ <12 GeV/${\it {c}}$ and 0-80%. The $\Lambda_{\rm {c}}^{+}$/${\rm D}^{0}$ ratio, which is sensitive to the charm quark hadronisation mechanisms in the medium, is measured and found to be larger than the ratio measured in minimum-bias pp collisions at $\sqrt{s} = 7$ TeV and in p-Pb collisions at $\sqrt{s_{\rm {NN}}} = 5.02$ TeV. In particular, the values in p-Pb and Pb-Pb collisions differ by about two standard deviations of the combined statistical and systematic uncertainties. The $\Lambda_{\rm {c}}^{+}$/${\rm D}^{0}$ ratio is also compared with model calculations including different implementations of charm quark hadronisation. The measured ratio is reproduced by models implementing a pure coalescence scenario, while adding a fragmentation contribution leads to an underestimation. The $\Lambda_{\rm {c}}^{+}$ nuclear modification factor, $R_\mathrm{AA}$, is also presented. The measured values of the $R_\mathrm{AA}$ of $\Lambda_{\rm {c}}^{+}$, ${\rm D}_{\rm {s}}$ and non-strange D mesons are compatible within the combined statistical and systematic uncertainties. They show, however, a hint of a hierarchy $R_\mathrm{AA}^{{\rm D}^{0}}

Abstract: CERN LHC. The WZ production cross section is measured by the CMS experiment at the CERN LHC in proton-proton collision data samples corresponding to integrated luminosities of 4.9 fb−1 collected at √s = 7 TeV, and 19.6 fb−1 at √s= 8 TeV. The measurements are performed using the fully-leptonic WZ decay modes with electrons and muons in the final state. The measured cross sections for 71 < mZ < 111 GeV are σ(pp → WZ; √s = 7 TeV) = 20.14 ± 1.32 (stat) ± 0.38 (theo) ± 1.06 (exp) ± 0.44 (lumi) pb and σ(pp → WZ; √s = 8 TeV) = 24.09 ± 0.87 (stat) ± 0.80 (theo) ± 1.40 (exp) ± 0.63 (lumi) pb. Differential cross sections with respect to the Z boson pT, the leading jet pT, and the number of jets are obtained using the √s = 8 TeV data. The results are consistent with standard model predictions and constraints on anomalous triple gauge couplings are obtained.

Abstract: Results of a search for nonresonant production of Higgs boson pairs, with each Higgs boson decaying to a bb pair, are presented. This search uses data from proton-proton collisions at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb^-1 , collected by the CMS detector at the LHC. No signal is observed, and a 95% confidence level upper limit of 847 fb is set on the cross section for standard model nonresonant Higgs boson pair production times the squared branching fraction of the Higgs boson decay to a bb pair. The same signature is studied, and upper limits are set, in the context of models of physics beyond the standard model that predict modified couplings of the Higgs boson.

Abstract: The BRAHMS collaboration has measured transverse momentum spectra of pions, kaons, protons, and antiprotons at rapidities 0 and 3 for Cu+Cu collisions at sNN=200 GeV. As the collisions become more central the collective radial flow increases while the temperature of kinetic freeze-out decreases. The temperature is lower and the radial flow weaker at forward rapidity. Pion and kaon yields with transverse momenta between 1.5 and 2.5 GeV/c are suppressed for central collisions relative to scaled p+p collisions. This suppression, which increases as the collisions become more central, is consistent with jet quenching models and is also present with comparable magnitude at forward rapidity. At such rapidities, initial state effects may also be present and persistence of the meson suppression to high rapidity may reflect a combination of jet quenching and nuclear shadowing. The ratio of protons to mesons increases as the collisions become more central and is largest at forward rapidities.

Abstract: Measurements of inclusive isolated-photon and photon+jet production in proton-proton collisions at $\sqrt{s} = 13\TeV$ are presented. The analysis uses data collected by the CMS experiment in 2015, corresponding to an integrated luminosity of 2.26\fbinv. The cross section for inclusive isolated photon production is measured as a function of the photon transverse energy in a fiducial region. The cross section for photon+jet production is measured as a function of the photon transverse energy in the same fiducial region with identical photon requirements and with the highest transverse momentum jet. All measurements are in agreement with predictions from next-to-leading-order perturbative QCD.

Abstract: CERN-LHC. A measurement for inclusive 2- and 3-jet events of the azimuthal correlation between the two jets with the largest transverse momenta, $\Delta\phi_{12}$, is presented. The measurement considers events where the two leading jets are nearly collinear ("back-to-back") in the transverse plane and is performed for several ranges of the leading jet transverse momentum. Proton-proton collision data collected with the CMS experiment at a center-of-mass energy of 13 TeV and corresponding to an integrated luminosity of 35.9 $\text{fb}^{-1}$ are used. Non-perturbative correction factors are estimated by evaluating the ratios of the predictions from PYTHIA8 tune CUETP8M1 including the simulation of multi-parton interaction and hadronization, to the predictions without considering these effects. The non-perturbative correction factors correspond to the analysis: "Azimuthal separation in nearly back-to-back jet topologies in inclusive 2- and 3-jet events in pp collisions at $\sqrt{s} = 13$ TeV".

Abstract: CERN-LHC. Measurements are presented of associated production of a W boson and a charm quark (W + c) in proton-proton collisions at a center-of-mass energy of 13 TeV. The data correspond to an integrated luminosity of 35.7 fb−1 collected by the CMS experiment at the CERN LHC. The W bosons are identified by their decay into a muon and a neutrino. The charm quarks are tagged via the full reconstruction of D∗(2010) mesons that decay via D∗(2010) --> D0 + pi \to K + pi + pi. A cross section is measured in the fiducial region defined by the muon transverse momentum pT(\mu) > 26 GeV, muon pseudorapidity |\eta(\mu)| < 2.4, and charm quark transverse momentum pT(c) > 5 GeV. The cross section is also measured differentially as a function of the pseudorapidity of the muon from the W boson decay, presented separately for W+, W- and the combination. The W + D∗(2010) cross section is determined with the additional constraint of |\eta(D*)| < 2.4 and without imposing restrictions on the origin of the D∗(2010) meson.

Abstract: This Letter describes a search for Higgs boson pair production using the combined results from four final states: \bbgg, \bbtt, \bbbb, and \bbvv, where V represents a $\PW$ or \PZ boson. The search is performed using data collected in 2016 by the CMS experiment from LHC proton-proton collisions at $\sqrt{s} = 13\TeV$, corresponding to an integrated luminosity of 35.9\fbinv.Limits are set on the Higgs boson pair production cross section. A 95\% confidence level observed (expected) upper limit on the nonresonant production cross section is set at 22.2\,(12.8) times the standard model value.A search for narrow resonances decaying to Higgs boson pairs is also performed in the mass range 250--3000\GeV. No evidence for a signal is observed, and upper limits are set on the resonance production cross section.

Abstract: Differential Higgs boson ($H$) production cross sections are sensitive probes for physics beyond the standard model. New physics may contribute in the gluon-gluon fusion loop, the dominant Higgs boson production mechanism at the LHC, and manifest itself through deviations from the distributions predicted by the standard model. Combined spectra for the $H\to\gamma\gamma$, $H\to ZZ$, and $H\to b \overline{b}$ decay channels and the inclusive Higgs boson production cross section are presented, based on proton-proton collision data recorded with the CMS detector at $\sqrt{s}=13$\TeV corresponding to an integrated luminosity of 35.9 fb${}^{-1}$. The transverse momentum spectrum is used to place limits on the Higgs boson couplings to the top, bottom, and charm quarks, as well as its direct coupling to the gluon field. No significant deviations from the standard model are observed in any differential distribution. The measured total cross section is $61.1\pm 6.0 \text{(stat)} \pm 3.7 \text{(syst)}$ pb, and the precision of the measurement of the differential cross section of the Higgs boson transverse momentum is improved by about 15% with respect to the $H\to\gamma\gamma$ channel alone.

Abstract: A search for a light charged Higgs boson ($\mathrm{H^{+}}$) decaying to a W boson and a CP-odd Higgs boson (A) in final states with $\mathrm{e}\mu\mu$ or $\mu\mu\mu$ is performed using data from pp collisions at $\sqrt{s}=13$ TeV, recorded by the CMS detector at the LHC and corresponding to an integrated luminosity of 35.9 fb$^{-1}$. In this search, it is assumed that the $\mathrm{H}^{+}$ boson is produced in decays of top quarks, and the A boson decays to two opposite-charge muons. The presence of signals for $\mathrm{H}^{+}$ boson masses between 100 and 160 GeV and A boson masses between 15 and 75 GeV is investigated. No evidence for the production of the $\mathrm{H^{+}}$ boson is found. Upper limits at 95% confidence level are obtained on the combined branching fraction for the decay chain, $\mathrm{t}\to\mathrm{bH^{+}}\to\mathrm{bW^{+}A}\to\mathrm{bW^{+}}\mu^{+}\mu^{-}$, of $1.9\times10^{-6}$ to $8.6\times10^{-6}$, depending on the masses of the $\mathrm{H^{+}}$ and A bosons. These are the first limits for these decay modes of the $\mathrm{H^{+}}$ and A bosons.

Abstract: A search is presented for additional scalar (H) or pseudoscalar (A) Higgs bosons decaying to a top quark pair in proton-proton collisions at a center-of-mass energy of 13 TeV. The data set analyzed corresponds to an integrated luminosity of 35.9 fb-1 collected by the CMS experiment at the LHC. Final states with one or two charged leptons are considered. The invariant mass of the reconstructed top quark pair system and variables that are sensitive to the spin of the particles decaying into the top quark pair are used to search for signatures of the H or A bosons. The interference with the standard model top quark pair background is taken into account. A moderate signal-like deviation compatible with an A boson with a mass of 400 GeV is observed with a global significance of 1.9 standard deviations. New stringent constraints are reported on the strength of the coupling of the hypothetical bosons to the top quark, with the mass of the bosons ranging from 400 to 750 GeV and their total relative width from 0.5 to 25%. The results of the search are also interpreted in a minimal supersymmetric standard model scenario. Values of m_A from 400 to 700 GeV are probed, and a region with values of tan(beta) below 1.0 to 1.5, depending on m_A, is excluded at 95% confidence level.

Abstract: Abstract: A study of the production of J/psi mesons in association with jets in proton-proton collisions at CM energy of 8~TeV is presented. The analysis is based on data corresponding to an integrated luminosity of 19.1 inverse femtobarns collected with the CMS detector at the LHC. For events with at least one observed jet, the angular separation between the J/psi meson and the jet is used to test whether the meson is a jet fragment. The differential distributions of the jet fragmentation probability as a function of jet energy for a fixed J/psi energy fraction are presented. The experimental results are compared to a theoretical model using the fragmenting jet function (FJF) approach. The jet fragmentation data agree with the predictions of the FJF calculations that use specific long-distance matrix element parameters. This agreement shows that the combination of data on jet fragmentation to J/psi mesons and FJF analysis is a new way to test predictions for J/psi meson production from nonrelativistic quantum chromodynamics. The results indicate that the jet fragmentation mechanism produces unpolarized J/psi mesons. The analysis also shows that most J/psi mesons with energy above 15 GeV and rapidity |y|<1.0 are fragments of jets with pseudorapidity < 1.

Abstract:
Unfolded normalized differential cross sections for angular observables sensitive to the top quark polarization and $t\bar{t}$ spin correlations measured in dileptonic $t\bar{t}$ events at CMS, and the corresponding extracted coefficients and values of $f_\text{SM}$.

Statistical and systematic covariance matrices are given for all measured bins (or coefficients) together, in the same order as the distributions are given on this page.

Care must be taken in the choice of distributions for simultaneous fitting. When using a simple $\chi^2$ minimization procedure, the statistical uncertainty in the fitted parameter can be reduced by adding to the fit an observable which has little or no sensitivity to the fitted parameter, but which is not independent of the other observables in the fit. This problem can be avoided by requiring the set of fitted observables to be mutually independent. For example, $\cos\theta_{1}^{k}$ and $\cos\theta_{1}^{k*}$ should not be used together, because $|\cos\theta_{1}^{k}|=|\cos\theta_{1}^{k*}|$.

Abstract: A search is presented for the production of a Higgs boson in association with a single top quark, based on data collected in 2016 by the CMS experiment at the LHC at a center-of-mass energy of 13 TeV, which corresponds to an integrated luminosity of 35.9 fb$^{-1}$. The production cross section for this process is highly sensitive to the absolute values of the top quark Yukawa coupling, $y_t$, the Higgs boson coupling to vector bosons, $g_{HVV}$, and, uniquely, to their relative sign. Analyses using multilepton signatures, targeting $H \to WW$, $H \to \tau\tau$, and $H \to ZZ$ decay modes, and signatures with a single lepton and a $b\bar{b}$ pair, targeting the $H \to b\bar{b}$ decay, are combined with a reinterpretation of a measurement in the $H \to \gamma\gamma$ channel to constrain $y_t$. For a standard model (SM) like value of $g_{HVV}$, the data favor positive values of $y_t$ and exclude values of $y_t$ below about -0.9 $y^{SM}_t$.

Abstract: CERN-LHC. The analysis searches for pairs of light pseudoscalar bosons, in the mass range from 4 to 15 GeV, produced from decays of the 125 GeV Higgs boson. The decay modes considered are final states that arise when one of the pseudoscalars decays to a pair of tau leptons, and the other one either into a pair of tau leptons or muons. The analysis employs a special analysis strategy to select and identify highly Lorentz-boosted muon or tau lepton pairs with overlapping decay products. This signature is sensitive to specific 2HD+1S models in which the lightest pseudoscalar boson (a) has a large singlet component, and therefore its couplings to SM particles are significantly reduced. The search is based on proton-proton collisions collected by the CMS experiment in 2016 at a center-of-mass energy of 13 TeV that correspond to an integrated luminosity of 35.9 fb-1. No significant excess is observed beyond the expectation from the SM. The table gives upper limits on the cross section times branching fraction for light pseudoscalars with masses between 4 and 15 GeV.

Abstract:
CERN-LHC. Search for new neutral Higgs bosons through the process where a heavy scalar(pseudoscalar) decays to a Z boson and a pseudoscalar(scalar), itself decaying to a pair of b quarks/anti-quarks. Based on a sample of proton-proton collisions at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity of 35.9 fb−1. Upper limits at 95% confidence level are set on the production cross section times branching fraction, with masses of the resonances ranging up to 1000 GeV. The results are interpreted in the context of the two-Higgs-doublet model.

The main background processes, in decreasing order of importance, are Z boson production through the Drell–Yan (DY) process and top quark pair production where both top quarks decay leptonically (fully leptonic tt). Single top quark, diboson, triboson, ttV (V = W, Z), W+jets, and SM Higgs boson production are also considered. The contribution from quantum chromodynamics (QCD) multijet events with jets misidentified as leptons constitutes a negligible background after requiring a pair of well-identified leptons. The dominant contribution arises from the production of a Z boson in association with two b quark jets, which yields the same final state as the signal process when the Z boson decays leptonically.

Simulated background samples are generated at next-to-leading order (NLO) precision in QCD. In particular, the DY, ttV, W+jets, triboson, and part of the diboson background samples are produced with MadGraph5 amc@nlo version 2.2.2.0 with the FxFx procedure for NLO jet merging and MAD SPIN to properly propagate spin information in the matrix element of the process. The tt, single top quark, SM Higgs boson production, and the remaining diboson background samples are produced with POWHEG version 2.

Simulated signal samples of 207 different mass hypotheses are produced with mH and mA ranging from 120 to 1000 GeV and from 30 to 1000 GeV, respectively. These samples are produced using MadGraph5 amc@nlo version 2.3.2 interfaced with the parton shower generator PYTHIA 8.212. The parton distribution function (PDF) set used is NNPDF 3.0 at leading order (LO) in the four-flavour scheme, and the factorisation and renormalisation scales are estimated dynamically. The underlying event tune is CUEPT8M1, derived from the MONASH tune.

Jets are reconstructed using a particle flow (PF) technique.
PF candidates are clustered to form jets using the anti-kT clustering algorithm with a distance parameter of 0.4.

Region of interest is defined as:
 - two leptons and two b-tagged jets

Abstract: A search for decays of the Higgs and $Z$ boson to pairs of $J/\psi$ or $\Upsilon(nS) (n = 1, 2, 3)$ mesons, with their subsequent decay to $\mu^+$ $\mu^−$ pairs, is presented. The analysis uses data from proton-proton collisions at $\sqrt{s} = 13$ TeV, collected with the CMS detector at the LHC in 2017 and corresponding to an integrated luminosity of 37.5 fb$^{−1}$ . While an observation of such a decay with this sample would indicate the presence of physics beyond the standard model, no significant excess is observed. Upper limits at 95% confidence level are placed on the branching fractions of these decays. In the $J/\psi$ pair channel, the limits are $1.8 \times 10^{-3}$ and $2.2 \times 10^{-6}$ for the Higgs and Z boson, respectively, while in the combined $\Upsilon(nS)$ pair channel, the limits are $1.8 \times 10^{-3}$ and $1.5 \times 10^{-6}$ , respectively, when the mesons from the Higgs and Z boson decay are assumed to be unpolarized. When fully longitudinal and transverse polarizations are considered the limits reduce by about $22–29$% and increase by about $10–13$%, respectively.

Abstract: A search for pair production of the supersymmetric partner of the top quark, the top squark, in proton-proton collision events at $ \sqrt{s} = 13\TeV $ is presented in a final state containing hadronically decaying tau leptons and large missing transverse momentum. This final state is highly sensitive to high-\tanb or higgsino-like scenarios in which decays of electroweak gauginos to tau leptons are dominant. The search uses a data set corresponding to an integrated luminosity of 77.2\fbinv, which was recorded with the CMS detector during 2016 and 2017. No significant excess is observed with respect to the background prediction. Exclusion limits at 95\% confidence level are presented in the top squark and lightest neutralino mass plane within the framework of simplified models, in which top squark masses up to 1100\GeV are excluded for a nearly massless neutralino.

Abstract: Two related searches for phenomena beyond the standard model (BSM) are performed using events with hadronic jets and significant transverse momentum imbalance. The results are based on a sample of proton-proton collisions at a center-of-mass energy of 13 TeV, collected by the CMS experiment at the LHC in 2016--2018 and corresponding to an integrated luminosity of 137 fb$^{-1}$. The first search is inclusive, based on signal regions defined by the hadronic energy in the event, the jet multiplicity, the number of jets identified as originating from bottom quarks, and the value of the kinematic variable $M_\mathrm{T2}$ for events with at least two jets. For events with exactly one jet, the transverse momentum of the jet is used instead. The second search looks in addition for disappearing tracks produced by BSM long-lived charged particles that decay within the volume of the tracking detector. No excess event yield is observed above the predicted standard model background. This is used to constrain a range of BSM models that predict the following: the pair production of gluinos and squarks in the context of supersymmetry models conserving $R$-parity, with or without intermediate long-lived charginos produced in the decay chain; the resonant production of a colored scalar state decaying to a massive Dirac fermion and a quark; or the pair production of scalar and vector leptoquarks each decaying to a neutrino and a top, bottom, or light-flavor quark. In most of the cases, the results obtained are the most stringent constraints to date.

Abstract: Results are reported from a search for supersymmetric particles in the final state with multiple jets and large missing transverse momentum. The search uses a sample of proton-proton collisions at $\sqrt{s}=13$ TeV collected with the CMS detector in 2016--2018, corresponding to an integrated luminosity of 137 fb$^{-1}$, representing essentially the full LHC Run 2 data sample. The analysis is performed in a four-dimensional search region defined in terms of the number of jets, the number of tagged bottom quark jets, the scalar sum of jet transverse momenta, and the magnitude of the vector sum of jet transverse momenta. No significant excess in the event yield is observed relative to the expected background contributions from standard model processes. Limits on the pair production of gluinos and squarks are obtained in the framework of simplified models for supersymmetric particle production and decay processes. Assuming the lightest supersymmetric particle to be a neutralino, lower limits on the gluino mass as large as 2000 to 2310 GeV are obtained at $95\%$ confidence level, while lower limits on the squark mass as large as 1190 to 1630 GeV are obtained, depending on the production scenario.

Abstract: CERN-LHC. ALICE Measurement of charged particles differential transverse momentum correlation function, $\Delta p_{\rm T}\Delta p_{\rm T}$, in Pb-Pb collisions at $\sqrt{s_{NN}}= 2.76$ TeV. The correlations are reported as a function of the relative pseudorapidity and azimuthal angle difference, $\Delta\varphi$. The $\Delta\varphi$ dependence is found to be largely independent of $\Delta\eta$ at $\Delta\eta > 0.9$. $\Delta p_{\rm T}\Delta p_{\rm T}$ exhibits a strong dependence on collision centrality that is qualitatively similar to that of number correlations, R2, previously reported. In 0-5% most central Pb--Pb collisions the two particle transverse momentum correlation function exhibits a cleartwo hump structure at the 'away-side', an indication of the dominance of triangular flow. Detailed comparison of R2 and $\Delta p_{\rm T}\Delta p_{\rm T}$ correlation functions utilizing Fourier decomposition show that the $\Delta p_{\rm T}\Delta p_{\rm T}$ correlations at $\Delta\eta > 0.9$ can be well reproduced by the flow ansatz, assuming that all the correlations are dominated by the anisotropic flow.

Abstract: CERN-LHC. Combined ATLAS and CMS measurements of the Higgs boson production and decay rates, as well as constraints on its couplings to vector bosons and fermions, are presented. The combination is based on the analysis of five production processes, namely gluon fusion, vector boson fusion, and associated production with a $W$ or a $Z$ boson or a pair of top quarks, and of the six decay modes $H \to ZZ, WW$, $\gamma\gamma, \tau\tau, bb$, and $\mu\mu$. All results are reported assuming a value of 125.09 GeV for the Higgs boson mass, the result of the combined measurement by the ATLAS and CMS experiments. The analysis uses the CERN LHC proton-proton collision data recorded by the ATLAS and CMS experiments in 2011 and 2012, corresponding to integrated luminosities per experiment of approximately 5 fb$^{-1}$ at $\sqrt{s}$=7 TeV and 20 fb$^{-1}$ at $\sqrt{s}$ = 8 TeV. The Higgs boson production and decay rates measured by the two experiments are combined within the context of three generic parameterisations: two based on cross sections and branching fractions, and one on ratios of coupling modifiers. Several interpretations of the measurements with more model-dependent parameterisations are also given. The combined signal yield relative to the Standard Model prediction is measured to be 1.09 $\pm$ 0.11. The combined measurements lead to observed significances for the vector boson fusion production process and for the $H \to \tau\tau$ decay of 5.4 and 5.5 standard deviations, respectively. The data are consistent with the Standard Model predictions for all parameterisations considered.

Abstract: CERN-LHC. Measurement of the angular correlations of identified particles (pions, kaons, protons, lambdas) in pp collisions at a center-of-mass energy of 7 TeV. Data for mesons exhibit an expected peak dominated by effects associated with mini-jets and are well reproduced by general purpose Monte Carlo generators. However, for baryon pairs, where both particles have the same baryon number, a near-side anti-correlation structure is observed instead of a peak. This result currently presents a challenge to Monte Carlo models and its origin remains an open question.

Abstract: CERN-LHC. The production cross sections of the prompt charmed mesons $\rm{D}^{0}$, $\rm{D}^{+}$, $\rm D^{*+}$ and $\rm D_{s}$ were measured at mid-rapidity in proton-proton collisions at a centre-of-mass energy $\sqrt{s_{\rm{NN}}}$=7 TeV with the ALICE detector at the Large Hadron Collider (LHC). D mesons were reconstructed from their decays $\rm{D^{0}}\rightarrow K\pi$, $\rm{D^{+}}\rightarrow K\pi\pi$, $\rm{D}^{*+}\rightarrow \rm{D}^{0}\pi\rightarrow K\pi\pi$, $\rm{D_{s}}\rightarrow\phi\pi\rightarrow K K \pi$ , and their charge conjugates. With respect to previous measurements in the same rapidity region, the coverage in transverse momentum pt is extended and the uncertainties are reduced by a factor of about two. The accuracy on the estimated total c-cbar production cross section is likewise improved. The measured $p_{\rm T}$-differential cross sections are compared with the results of three perturbative QCD calculations.

Abstract: CERN-LHC-ALICE. We present a measurement of azimuthal correlations between inclusive J/$\psi$ and charged hadrons in p-Pb collisions recorded with the ALICE detector at the CERN LHC. The J/$\psi$ are reconstructed at forward (2.03 < y < 3.53) and backward (-4.46 < y < -2.96) rapidity via their $\mu^+\mu^-$ decay channel, while the charged hadrons are reconstructed at mid-rapidity ($|\eta|$ < 1.8). The correlations are expressed in terms of associated charged-hadron yields per J/$\psi$ trigger. A rapidity gap of at least 1.5 units between the trigger J/$\psi$ and the associated charged hadrons is required. Possible correlations due to collective effects are assessed by subtracting the associated per-trigger yields in the low-multiplicity collisions from those in the high-multiplicity collisions. After the subtraction, we observe a strong indication of remaining symmetric structures at $\Delta\varphi$ $\approx$ 0 and $\Delta\varphi$ $\approx$ $\pi$, similar to those previously found in two-particle correlations at middle and forward rapidity. The corresponding second-order Fourier coefficient ($v_2$) in the transverse momentum interval between 3 and 6 GeV/c is found to be positive with a significance of about 5$\sigma$. The obtained results are similar to the J/$\psi$ $v_2$ coefficients measured in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV, suggesting a common mechanism at the origin of the J/$\psi$ $v_2$.

Abstract: A search for supersymmetry is presented based on multijet events with large missing transverse momentum produced in proton-proton collisions at a center-of-mass energy of $\sqrt{s}=13~\mathrm{TeV}$. The data, corresponding to an integrated luminosity of $35.9~\mathrm{fb}^{-1}$, were collected with the CMS detector at the CERN LHC in 2016. The analysis utilizes four-dimensional exclusive search regions defined in terms of the number of jets, the number of tagged bottom quark jets, the scalar sum of jet transverse momenta, and the magnitude of the vector sum of jet transverse momenta. No evidence for a significant excess of events is observed relative to the expectation from the standard model. Limits on the cross sections for the pair production of gluinos and squarks are derived in the context of simplified models. Assuming the lightest supersymmetric particle to be a weakly interacting neutralino, 95% confidence level lower limits on the gluino mass as large as 1800 to 1960 GeV are derived, and on the squark mass as large as 960 to 1390 GeV, depending on the production and decay scenario.

Abstract: A measurement is presented of the triple-differential dijet cross section at a centre-of-mass energy of 8 TeV using 19.7 fb$^-1$ of data collected with the CMS detector in proton-proton collisions at the LHC. The cross section is measured as a function of the average transverse momentum, half the rapidity separation, and the boost of the two leading jets in the event. The cross section is corrected for detector effects and compared to calculations in perturbative quantum chromodynamics at next-to-leading order accuracy, complemented with electroweak and nonperturbative corrections. New constraints on parton distribution functions are obtained and the inferred value of the strong coupling constant is $\alpha_s(M_{Z})$ = 0.1199 $\pm$ 0.0015 (exp)$^{+0.0031}_{-0.0020}$ (theo), where M$_{Z}$ is the mass of the Z boson.

The search uses a sample of proton-proton collision data at sqrt{s}= 13 TeV recorded by the CMS experiment at the LHC, corresponding to an integrated luminosity of 35.9 fb−1. The observed event yields in the signal regions are consistent with those expected from standard model backgrounds. The results are interpreted in the context of simplified models of supersymmetry involving gluino pair production, with gluino decay into either on- or off-mass-shell top squarks. Assuming that the top squarks decay into a top quark plus a stable, weakly interacting neutralino, scenarios with gluino masses up to about 1.9 TeV are excluded at 95% confidence level for neutralino masses up to about 1 TeV.

Abstract: A search for top squark pair production in pp collisions at $\sqrt{s}=13$ TeV is performed using events with a single isolated electron or muon, jets, and a large transverse momentum imbalance. The results are based on data collected in 2016 with the CMS detector at the LHC, corresponding to an integrated luminosity of 35.9 $\text{fb}^\text{$-$1}$. No significant excess of events is observed above the expectation from standard model processes. Exclusion limits are set in the context of supersymmetric models of pair production of top squarks that decay either to a top quark and a neutralino or to a bottom quark and a chargino. Depending on the details of the model, we exclude top squarks with masses as high as 1120 GeV. Detailed information is also provided to facilitate theoretical interpretations in other scenarios of physics beyond the standard model.

Abstract: CERN-LHC. A search for physics beyond the standard model in final states with at least one photon, large transverse momentum imbalance, and large total transverse event activity is presented. Such topologies can be produced in gauge-mediated supersymmetry models in which pair-produced gluinos or squarks decay to photons and gravitinos via short-lived neutralinos. The data sample corresponds to an integrated luminosity of 35.9 fbinv of proton--proton collisions at sqrt(s)=13 TeV recorded by the CMS experiment at the LHC in 2016. No significant excess of events above the expected standard model background is observed. The data are interpreted in simplified models of gluino and squark pair production, in which gluinos or squarks decay via neutralinos to photons. Gluino masses of up to 1.50-2.00 TeV and squark masses up to 1.30-1.65 TeV are excluded at 95% confidence level, depending on the neutralino mass and branching fraction.

Abstract:
CERN-LHC. Search for top squarks and dark matter particles in opposite-charge dilepton final states at sqrt(s) = 13 TeV

A search for new physics is presented in final states with two oppositely charged leptons (electrons or muons), jets identified as originating from b quarks, and missing transverse momentum (pTmiss).
The search uses proton-proton collision data at 13 TeV amounting to 35.9 $fb^{−1}$ of integrated luminosity collected using the CMS detector in 2016.
Hypothetical signal events are efficiently separated from the dominant ttbar background with requirements on pTmiss and transverse mass variables.
No significant deviation is observed from the expected background.
Exclusion limits are set in the context of simplified supersymmetric models with pair-produced top squarks.
For top squarks, decaying exclusively to a top quark and a neutralino, exclusion limits are placed at 95% confidence level on the mass of the lightest top squark up to 800 GeV and on the lightest neutralino up to 360 GeV.
These results, combined with searches in the single-lepton and all-jet final states, raise the exclusion limits up to 1050 GeV for the lightest top squark and up to 500 GeV for the lightest neutralino.
For top squarks undergoing a cascade decay through charginos and sleptons, the mass limits reach up to 1300 GeV for top squarks and up to 800 GeV for the lightest neutralino.
The results are also interpreted in a simplified model with a dark matter (DM) particle coupled to the top quark through a scalar or pseudoscalar mediator.
For light DM, mediator masses up to 100 (50) GeV are excluded for scalar (pseudoscalar) mediators.
The result for the scalar mediator achieves some of the most stringent limits to date in this model.

Abstract: CERN-LHC. CMS. A search for supersymmetry is presented based on proton-proton collision events containing identified hadronically decaying top quarks, no leptons, and an imbalance pT_miss in transverse momentum. 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 35.9 fb−1. Search regions are defined in terms of the multiplicity of bottom quark jet and top quark candidates, the pT_miss, the scalar sum of jet transverse momenta, and the mT2 mass variable. No statistically significant excess of events is observed relative to the expectation from the standard model. Lower limits on the masses of supersymmetric particles are determined at 95% confidence level in the context of simplified models with top quark production. For a model with direct top squark pair production followed by the decay of each top squark to a top quark and a neutralino, top squark masses up to 1020 GeV and neutralino masses up to 430 GeV are excluded. For a model with pair production of gluinos followed by the decay of each gluino to a top quark-antiquark pair and a neutralino, gluino masses up to 2040 GeV and neutralino masses up to 1150 GeV are excluded. These limits extend previous results.

Abstract: CERN-LHC. Differential cross sections for a W boson produced in association with jets are measured in a data sample of proton-proton collisions at a center-of-mass energy of 13 TeV recorded with the CMS detector and corresponding to an integrated luminosity of 2.2 inverse femtobarns. The W bosons are identified through their decay into a muon and a neutrino. The cross sections are reported as functions of jet multiplicity, jet transverse momenta, jet rapidity, the scalar sum of jet transverse momenta (HT), and angular correlations between the muon and each jet for different jet multiplicities. The cross sections are measured in the fiducial region defined by a muon with pT > 25 GeV and pseudorapidity |eta| < 2.4, and by a transverse mass between the muon and the missing transverse energy MT > 50 GeV. Jets are reconstructed using the anti-kT algorithm with a distance parameter R = 0.4, and only jets with pT > 30 GeV, rapidity |y| < 2.4, and a separation of deltaR > 0.4 from the muon are considered. In addition, the differential cross section is measured as a function of the angular distance (DeltaR) between the muon and the closest jet for events with one or more jets, requiring jets with pT > 100 GeV and the leading jet with pT > 300 GeV.

Abstract: Searches are presented for resonances decaying to dijet final states in proton-proton collisions at $\sqrt{s}=13~\mathrm{TeV}$. A low-mass search, for a resonance mass between 0.6 and 1.6 TeV, is performed using dijets reconstructed at the trigger level with calorimeter information, in a data set corresponding to an integrated luminosity of $27~\mathrm{fb}^{-1}$. A high-mass search, for resonances above 1.6 TeV, is performed using dijets reconstructed with the particle-flow algorithm in a data set corresponding to $36~\mathrm{fb}^{-1}$. The dijet mass spectrum is well described by a smooth parameterization and no significant evidence for the production of new particles is observed. Upper limits at $95\%$ confidence level are reported on the production cross section for narrow resonances with masses above 0.6 TeV. In the context of specific models, the limits exclude string resonances with masses below 7.7 TeV, scalar diquarks below 7.2 TeV, axigluons and colorons below 6.1 TeV, excited quarks below 6.0 TeV, color-octet scalars below $3.4~\mathrm{TeV}$, W$^{\prime}$ bosons below 3.3 TeV, Z$^{\prime}$ bosons below 2.7 TeV, RS gravitons below $1.7~\mathrm{TeV}$ and between 2.1 and 2.5 TeV, and dark matter mediators below 2.6 TeV. The limits on both vector and axial-vector mediators, in a simplified model of interactions between quarks and dark matter, are also presented as functions of dark matter mass and coupling to quarks. Limits are presented for resonances with intrinsic width as large as $30\%$ of the resonance mass, and are used to improve and extend the exclusions of a dark matter mediator to larger values of mass and coupling.

Abstract:
Measurement of the underlying event activity, in proton-proton collisions at a centre-of-mass energy of 13 TeV, performed using inclusive Z-boson events collected by the CMS experiment at the Large Hadron Collider. The analyzed data corresponds to an integrated luminosity of 2.1 fb-1. The underlying event activity is quantified in terms of charged particle multiplicity and their scalar sum of their transverse momentum in different topological regions defined with respect to the resultatnt azimuthal direction of the two muons coming from the decay of a Z-boson. The distributions are unfolded to stable charged-particle level and are compared with predictions from various simulations, as well as with the measurements at a centre-of-mass energy of 1.96 TeV and 7 TeV by the CDF and CMS experiments.
Events are selected online by requiring the presence of at least two isolated muon candidates with - $p_T > 17\,(8)$ GeV for the leading (subleading) muon - Offline, the leading and subleading muons are required to have a $p_T$ larger than 20 and 10 GeV, respectively - Events with two oppositely charged muons are further required to have an invariant mass ($M_{\mu\mu}$) in the window 81--101 GeV. - All charged particles, except selected muons, with $p_T > 0.5 GeV$ and $|\eta| < 2 $ are considered for the UE study.

Abstract: A search for charged Higgs bosons produced via vector boson fusion and decaying into $W^{\pm}$ and $Z$ bosons using proton-proton collisions at $\sqrt{s}=13$ TeV is presented. The data sample corresponds to an integrated luminosity of 15.2\fbinv collected with the CMS detector in 2015 and 2016. The event selection requires three leptons (electrons or muons), two jets with large pseudorapidity separation and high dijet mass, and missing transverse momentum. The observation agrees with the standard model prediction. Limits on the vector boson fusion production cross section times branching fraction for new charged physical states are reported as a function of mass from 200 to 2000 GeV and interpreted in the context of Higgs triplet models.

Abstract: A search for new physics using events containing an imbalance in transverse momentum and one or more energetic jets arising from initial-state radiation or the hadronic decay of W or Z bosons is presented. A data sample of proton-proton collisions at $\sqrt{s} = 13$ TeV, collected with the CMS detector at the LHC and corresponding to an integrated luminosity of 35.9 fb$^{−1}$, is used. The observed data are found to be in agreement with the expectation from standard model processes. The results are interpreted as limits on the dark matter production cross section in simplified models with vector, axial-vector, scalar, and pseudoscalar mediators. Interpretations in the context of fermion portal and nonthermal dark matter models are also provided. In addition, the results are interpreted in terms of invisible decays of the Higgs boson and set stringent limits on the fundamental Planck scale in the Arkani-Hamed, Dimopoulos, and Dvali model with large extra spatial dimensions.

Abstract: CERN-LHC. The nuclear modification factors of J/psi and psi(2S) mesons are measured in PbPb collisions at a centre-of-mass energy per nucleon pair of 5.02 TeV. The analysis is based on PbPb and pp data samples collected by CMS at the LHC in 2015, corresponding to integrated luminosities of 464 inverse microbarns and 28 inverse picobarns, respectively. The measurements are performed in the dimuon rapidity range of abs(y)< 2.4 as a function of centrality, rapidity, and transverse momentum (pT) from pT= 3 GeV/c in the most forward region and up to 50 GeV/c. Both prompt and nonprompt (coming from b hadron decays) J/psi mesons are observed to be increasingly suppressed with centrality, with a magnitude similar to the one observed at 2.76 TeV for the two J/psi meson components. No dependence on rapidity is observed for either prompt or nonprompt J/psi mesons. An indication of a lower prompt J/psi meson suppression at pT > 25 GeV/c is seen with respect to that observed at intermediate pT. The prompt psi(2S) meson yield is found to be more suppressed than that of the prompt J/psi mesons in the entire pT range.

Abstract: CERN-LHC. CMS. Results are reported from a search for physics beyond the standard model in proton–proton collisions at a center-of-mass energy of sqrt{s}=13 TeV. The search uses a signature of a single lepton, large jet and bottom quark jet multiplicities, and high sum of large-radius jet masses, without any requirement on the missing transverse momentum in an event. The data sample corresponds to an integrated luminosity of 35.9 fb−1 recorded by the CMS experiment at the LHC. No significant excess beyond the prediction from standard model processes is observed. The results are interpreted in terms of upper limits on the production cross section for R-parity violating supersymmetric extensions of the standard model using a benchmark model of gluino pair production, in which each gluino decays promptly via gluino->tbs. Gluinos with a mass below 1610 GeV are excluded at 95% confidence level.

Abstract: CERN-LHC. Normalized differential cross sections for top quark pair production are measured in the dilepton (e-e, mu-mu, and mu-e) decay channels in proton-proton collisions at a center-of-mass energy of 13 TeV. The measurements are performed with data corresponding to an integrated luminosity of 2.1 inverse-femtobarns using the CMS detector at the LHC. The cross sections are measured differentially as a function of the kinematic properties of the leptons, jets from bottom quark hadronization, top quarks, and top quark pairs at the particle and parton levels. The results are compared to several Monte Carlo generators that implement calculations up to next-to-leading order in perturbative quantum chromodynamics interfaced with parton showering, and also to fixed-order theoretical calculations of top quark pair production up to next-to-next-to-leading order.

0.55$\pm$0.02(tot) in the $\rm{e}^\pm \mu^\mp$ and 0.57$\pm$0.04(tot) in the $\mu^\pm \mu^\mp$ channel, respectively

In both the $\ell$+jets and dilepton analyses, events with $\tau$ leptons are considered as signal if they decay to electrons or muons that satisfy the selection requirements, and are included in the simulation.

Abstract: The $p_{\rm {T}}$-differential production cross section of prompt $\Lambda_{\rm {c}}^{+}$ charmed baryons was measured with the ALICE detector at the Large Hadron Collider (LHC) in pp collisions at $\sqrt{s} = 7$ TeV and in p-Pb collisions at $\sqrt{s_{\rm {NN}}} = 5.02$ TeV at midrapidity. The $\Lambda_{\rm {c}}^{+}$ and $\Lambda_{\rm {c}}^{-}$ were reconstructed in the hadronic decay modes $\Lambda_{\rm {c}}^{+} \to {\rm p} {\rm K}^{-}\pi^{+}$, $\Lambda_{\rm {c}}^{+} \to {\rm p} {\rm K}^{0}_{S}$ and in the semileptonic channel $\Lambda_{\rm {c}}^{+}\to e^{+} \nu_{e} \Lambda$ (and charge conjugates). The measured values of the $\Lambda_{\rm {c}}^{+}$/${\rm D}^{0}$ ratio, which is sensitive to the c-quark hadronisation mechanism, and in particular to the production of baryons, are presented and are larger than those measured previously in different colliding systems, centre-of-mass energies, rapidity and $p_{\rm {T}}$ intervals, where the $\Lambda_{\rm {c}}^{+}$ production process may differ. The results are compared with the expectations obtained from perturbative Quantum Chromodynamics calculations and Monte Carlo event generators. Neither perturbative QCD calculations nor Monte Carlo models reproduce the data, indicating that the fragmentation of heavy-flavour baryons is not well understood. The first measurement at the LHC of the $\Lambda_{\rm {c}}^{+}$~nuclear modification factor, $R_\mathrm{pPb}$, is also presented. The $R_\mathrm{pPb}$ is found to be consistent with unity and with that of D mesons within the uncertainties, and consistent with a theoretical calculation that includes cold nuclear matter effects and a calculation that includes charm quark interactions with a deconfined medium.

Abstract: The first observation of electroweak production of same-sign W boson pairs in proton-proton collisions is reported. The data sample corresponds to an integrated luminosity of 35.9fb-1 collected at a center-of-mass energy of 13TeV with the CMS detector at the LHC. Events are selected by requiring exactly two leptons (electrons or muons) of the same charge, moderate missing transverse momentum, and two jets with a large rapidity separation and a large dijet mass. The observed significance of the signal is 5.5 standard deviations, where a significance of 5.7 standard deviations is expected based on the standard model. The ratio of measured event yields to that expected from the standard model at leading-order is 0.90 +/- 0.22. A cross section measurement in a fiducial region is reported. Bounds are given on the structure of quartic vector boson interactions in the framework of dimension-eight effective field theory operators and on the production of doubly charged Higgs bosons.

Abstract: CERN-LHC-ALICE. A measurement of beauty hadron production at mid-rapidity in proton-lead collisions at a nucleon-nucleon centre-of-mass energy $\sqrt{s_{\rm NN}}=5.02$ TeV is presented. The semi-inclusive decay channel of beauty hadrons into J/$\psi$ is considered, where the J/$\psi$ mesons are reconstructed in the dielectron decay channel at mid-rapidity down to transverse momenta of 1.3 GeV/$c$. The ${\rm {b\overline{b}}}$ production cross section at mid-rapidity, ${\rm d}\sigma_{\rm {b\overline{b}}}/{\rm d} y$, and the total cross section extrapolated over full phase space, $\sigma_{\rm {b\overline{b}}}$, are obtained. This measurement is combined with results on inclusive J/$\psi$ production to determine the prompt J/$\psi$ cross sections. The results in p-Pb collisions are then scaled to expectations from pp collisions at the same centre-of-mass energy to derive the nuclear modification factor $R_{\rm pPb}$, and compared to models to study possible nuclear modifications of the production induced by cold nuclear matter effects. $R_{\rm pPb}$ is found to be smaller than unity at low $p_{\rm T}$ for both J/$\psi$ coming from beauty hadron decays and prompt J/$\psi$.

Abstract: CERN LHC. A measurement of vector boson scattering and constraints on anomalous quartic gauge couplings from events with two Z bosons and two jets are presented. The analysis is based on a data sample of proton-proton collisions at √s= 13 TeV collected with the CMS detector and corresponding to an integrated luminosity of 35.9 fb−1. The measurement is performed in the decay channel where each Z boson decays to either a pair of electrons or a pair of muons. The fiducial region is defined as: ptLepton > 5 GeV, |etaLepton|< 2.5,pTj1 > 30 GeV, |etaj1| < 4.7, pTj2 > 30 GeV, |etaj2|< 4.7, mjj > 100 GeV.
