Search for new phenomena in events with high jet multiplicity and low missing transverse momentum in proton–proton collisions at √s = 8 TeV
(2017)Physics Letters BA dedicated search is presented for new phenomena in inclusive 8- and 10-jet final states with low missing transverse momentum, with and without identification of jets originating from b quarks. The analysis is based on data from proton–proton collisions corresponding to an integrated luminosity of 19.7fb−1 collected with the CMS detector at the LHC at s=8TeV. The dominant multijet background expectations are obtained from low jet ...Journal Article -
Search for new phenomena with the MT2 variable in the all-hadronic final state produced in proton–proton collisions at √s=13 TeV
(2017)The European Physical Journal CA search for new phenomena is performed using events with jets and significant transverse momentum imbalance, as inferred through the MT2 variable. The results are based on a sample of proton–proton collisions collected in 2016 at a center-of-mass energy of 13TeV with the CMS detector and corresponding to an integrated luminosity of 35.9fb-1. No excess event yield is observed above the predicted standard model background, and the results ...Journal Article -
Search for single production of a heavy vector-like T quark decaying to a Higgs boson and a top quark with a lepton and jets in the final state
(2017)Physics Letters BA search for single production of vector-like top quark partners (T) decaying into a Higgs boson and a top quark is performed using data from pp collisions at a centre-of-mass energy of 13 TeV collected by the CMS experiment at the CERN LHC, corresponding to an integrated luminosity of 2.3 fb−1. The top quark decay includes an electron or a muon while the Higgs boson decays into a pair of b quarks. No significant excess over standard model ...Journal Article -
Relative Modification of Prompt psi(2S) and J/psi Yields from pp to PbPb Collisions at root(S)(NN)=5.02 TeV
(2017)Physical Review LettersThe relative modification of the prompt ψ(2S) and J/ψ yields from pp to PbPb collisions, at the center-of-mass energy of 5.02 TeV per nucleon pair, is presented. The analysis is based on pp and PbPb data samples collected by the CMS experiment at the LHC in 2015, corresponding to integrated luminosities of 28.0 pb−1 and 464 μb−1, respectively. The double ratio of measured yields of prompt charmonia reconstructed through their decays ...Journal Article -
Measurement of the top quark mass using single top quark events in proton-proton collisions at s√=8 TeV
(2017)The European Physical Journal CA measurement of the top quark mass is reported in events containing a single top quark produced via the electroweak t channel. The analysis is performed using data from proton-proton collisions collected with the CMS detector at the LHC at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 19.7 fb−1. Top quark candidates are reconstructed from their decay to a W boson and a b quark, with the W boson decaying ...Journal Article -
Observation of the decay B+→ψ(2S)ϕ(1020)K+ in pp collisions at s√= 8 TeV
(2017)Physics Letters BThe decay B+ -> psi(2S) phi(1020) K+ is observed for the first time using data collected from pp collisions at root S = 8 TeV by the CMS experiment at the LHC, corresponding to an integrated luminosity of 19.6 fb(-1). The branching fraction of this decay is measured, using the mode B+ -> psi(2S) K+ as normalization, to be (4.0 +/- 0.4 (stat)+/- 0.6 (syst)+/- 0.2 (B)) x 10(-6), where the third uncertainty is from the measured branching ...Journal Article -
Search for Charged Higgs Bosons Produced via Vector Boson Fusion and Decaying into a Pair of W and Z Bosons Using pp Collisions at √s=13 TeV
(2017)Physical Review LettersA search for charged Higgs bosons produced via vector boson fusion and decaying into W and Z bosons using proton-proton collisions at root s = 13 TeV is presented. The data sample corresponds to an integrated luminosity of 15.2 fb(-1) 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 ...Journal Article -
Search for narrow resonances in dilepton mass spectra in proton-proton collisions at s√ = 13 TeV and combination with 8 TeV data
(2017)Physics Letters BA search for narrow resonances in dielectron and dimuon invariant mass spectra has been performed using data obtained from proton–proton collisions at √s = 13TeV collected with the CMS detector. The integrated luminosity for the dielectron sample is 2.7 fb−1 and for the dimuon sample 2.9 fb−1. The sensitivity of the search is increased by combining these data with a previously analyzed set of data obtained at √s = 8TeV and corresponding ...Journal Article -
Measurement of the total and differential inclusive B+ hadron cross sections in pp collisions at √s = 13 TeV
(2017)Physics Letters BThe differential cross sections for inclusive production of B+ hadrons are measured as a function of the B+ transverse momentum pTB and rapidity yB in pp collisions at a centre-of-mass energy of 13 TeV, using data collected by the CMS experiment that correspond to an integrated luminosity of 48.1 pb−1.
