The second-order azimuthal anisotropy Fourier harmonics, v2, are obtained in p-Pb and PbPb collisions over a wide pseudorapidity (η) range based on correlations among six or more charged particles. The p-Pb data, corresponding to an integrated luminosity of 35  nb-1, were collected during the 2013 LHC p-Pb run at a nucleon-nucleon center-of-mass energy of(More)
A search for new long-lived particles decaying to leptons is presented using proton-proton collisions produced by the LHC at √[s]=8  TeV. Data used for the analysis were collected by the CMS detector and correspond to an integrated luminosity of 19.7  fb(-1). Events are selected with an electron and muon with opposite charges that both have transverse(More)
Measurements of the differential and double-differential Drell–Yan cross sections in the dielectron and dimuon channels are presented. They are based on proton– proton collision data at √ s = 8 TeV recorded with the CMS detector at the LHC and corresponding to an integrated luminosity of 19.7 fb −1. The measured inclusive cross section in the Z peak region(More)
The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. Abstract A search for a standard model Higgs boson produced in association with a top-quark pair and decaying to bottom quarks is presented. Events with hadronic jets and one or two oppositely charged leptons are selected from a data sample(More)
Properties of the Higgs boson with mass near 125 GeV are measured in proton-proton collisions with the CMS experiment at the LHC. Comprehensive sets of production and decay measurements are combined. The decay channels include γ γ , ZZ, WW, τ τ , bb, and μμ pairs. The data samples were collected in 2011 and 2012 and correspond to integrated luminosities of(More)
Transverse momentum spectra of charged particles are measured by the CMS experiment at the CERN LHC in pPb collisions at √ s NN = 5.02 TeV, in the range 0.4 < p T < 120 GeV/c and pseudorapidity |η cm | < 1.8 in the proton–nucleon center-of-mass frame. For p T < 10 GeV/c, the charged-particle production is asymmetric about η cm = 0, with smaller yield(More)
The purely electroweak (EW) cross section for the production of two jets in association with a Z boson, in proton–proton collisions at √ s = 8 TeV, is measured using data recorded by the CMS experiment at the CERN LHC, corresponding to an integrated luminosity of 19.7 fb −1. The electroweak cross section for the jj final state (with = e or μ and j(More)
A search has been performed for long-lived particles that could have come to rest within the CMS detector, using the time intervals between LHC beam crossings. The existence of such particles could be deduced from observation of their decays via energy deposits in the CMS calorime-ter appearing at times that are well separated from any proton–proton(More)
This paper presents distributions of topological observables in inclusive three-and four-jet events produced in pp collisions at a centre-of-mass energy of 7 TeV with a data sample collected by the CMS experiment corresponding to a luminosity of 5.1 fb −1. The distributions are corrected for detector effects, and compared with several event generators based(More)
Stringent limits are set on the long-lived lepton-like sector of the phenomenological minimal supersymmetric standard model (pMSSM) and the anomaly-mediated super-symmetry breaking (AMSB) model. The limits are derived from the results presented in a recent search for long-lived charged particles in proton–proton collisions, based on data collected by the(More)
