Centrality and pseudorapidity dependence of the transverse energy density in pPb collisions ats root s(NN)=5.02 TeV
(2019)Physical Review CThe almost hermetic coverage of the CMS detector is used to measure the distribution of transverse energy, ET, over 13.2 units of pseudorapidity, η, for pPb collisions at a center-of-mass energy per nucleon pair of √sNN=5.02TeV. The huge angular acceptance exploits the fact that the CASTOR calorimeter at −6.6<η<−5.2 is effectively present on both sides of the colliding system because of a switch in the proton-going and lead-going beam ...Journal Article -
Measurement of the t t ¯ production cross section, the top quark mass, and the strong coupling constant using dilepton events in pp collisions at √s=13Te
(2019)The European Physical Journal CA measurement of the top quark–antiquark pair production cross section σtt¯ in proton–proton collisions at a centre-of-mass energy of 13TeV is presented. The data correspond to an integrated luminosity of 35.9fb−1, recorded by the CMS experiment at the CERN LHC in 2016. Dilepton events (e ± μ ∓, μ+μ−, e+e−) are selected and the cross section is measured from a likelihood fit. For a top quark mass parameter in the simulation of mMCt=172.5GeV ...Journal Article -
Search for resonant production of second-generation sleptons with same-sign dimuon events in proton–proton collisions at √s=13TeV
(2019)The European Physical Journal CA search is presented for resonant production of second-generation sleptons (μ˜L, ν˜μ) via the R-parity-violating coupling λ′211 to quarks, in events with two same-sign muons and at least two jets in the final state. The smuon (muon sneutrino) is expected to decay into a muon and a neutralino (chargino), which will then decay into a second muon and at least two jets. The analysis is based on the 2016 data set of proton-proton collisions ...Journal Article -
Measurement of electroweak WZ boson production and search for new physics in WZ + two jets events in pp collisions at s=13TeV
(2019)Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy PhysicsA measurement of WZ electroweak (EW) vector boson scattering is presented. The measurement is performed in the leptonic decay modes WZ→lνl′l′, where l,l′=e,μ. The analysis is based on a data sample of proton-proton collisions at s=13TeV at the LHC collected with the CMS detector and corresponding to an integrated luminosity of 35.9 fb−1. The WZ plus two jet production cross section is measured in fiducial regions with enhanced contributions ...Journal Article -
Search for pair-produced three-jet resonances in proton-proton collisions at root s=13 TeV
(2019)Physical Review DA search has been performed for pair-produced resonances decaying into three jets. The proton-proton collision data used for this analysis were collected with the CMS detector in 2016 at a center-of-mass energy of 13 TeV and correspond to an integrated luminosity of 35.9 fb−1. The mass range from 200 to 2000 GeV is explored in four separate mass regions. The observations show agreement with standard model expectations. The results are ...Journal Article -
Measurement of the top quark mass in the all-jets final state at √s=13TeV and combination with the lepton+jets channel
(2019)The European Physical Journal CA top quark mass measurement is performed using 35.9fb−1 of LHC proton–proton collision data collected with the CMS detector at s√=13TeV. The measurement uses the tt¯ all-jets final state. A kinematic fit is performed to reconstruct the decay of the tt¯ system and suppress the multijet background. Using the ideogram method, the top quark mass (mt) is determined, simultaneously constraining an additional jet energy scale factor (JSF). The ...Journal Article -
A search for pair production of new light bosons decaying into muons in proton-proton collisions at 13 TeV
(2019)Physics Letters BA search for new light bosons decaying into muon pairs is presented using a data sample corresponding to an integrated luminosity of 35.9fb−1 of proton-proton collisions at a center-of-mass energy s=13TeV, collected with the CMS detector at the CERN LHC. The search is model independent, only requiring the pair production of a new light boson and its subsequent decay to a pair of muons. No significant deviation from the predicted background ...Journal Article -
Search for dark matter in events with a leptoquark and missing transverse momentum in proton-proton collisions at 13 TeV
(2019)Physics Letters BA search is presented for dark matter in proton-proton collisions at a center-of-mass energy of s=13 TeV using events with at least one high transverse momentum (pT) muon, at least one high-pT jet, and large missing transverse momentum. The data were collected with the CMS detector at the CERN LHC in 2016 and 2017, and correspond to an integrated luminosity of 77.4 fb−1. In the examined scenario, a pair of scalar leptoquarks is assumed ...Journal Article -
