Evidence for transverse momentum and pseudorapidity dependent event plane fluctuations in PbPb and pPb collisions
(2015)Physical Review CA systematic study of the factorization of long-range azimuthal two-particle correlations into a product of single-particle anisotropies is presented as a function of pT and η of both particles and as a function of the particle multiplicity in PbPb and pPb collisions. The data were taken with the CMS detector for PbPb collisions at √sNN=2.76 TeV and pPb collisions at √sNN=5.02 TeV, covering a very wide range of multiplicity. Factorization ...Journal Article -

Search for the standard model Higgs boson produced through vector boson fusion and decaying to bb
(2015)Physical Review DA first search is reported for a standard model Higgs boson (H) that is produced through vector boson fusion and decays to a bottom-quark pair. Two data samples, corresponding to integrated luminosities of 19.8 fb−1 and 18.3 fb−1 of proton-proton collisions at √s=8 TeV were selected for this channel at the CERN LHC. The observed significance in these data samples for a H→b¯b signal at a mass of 125 GeV is 2.2 standard deviations, while ...Journal Article -
Search for long-lived charged particles in proton-proton collisions at s√= 13 TeV
(2016)Physical Review DResults are presented of a search for heavy stable charged particles produced in proton-proton collisions at √s = 13 TeV using a data sample corresponding to an integrated luminosity of 2.5 fb-1 collected in 2015 with the CMS detector at the CERN LHC. The search is conducted using signatures of anomalously high energy deposits in the silicon tracker and long time-of-flight measurements by the muon system. The data are consistent with the ...Journal Article -
Measurement of the tt ̄ production cross section in pp collisions at 7 TeV in lepton+jets events using b-quark jet identification
(2011)Physical Review DA new measurement of the inclusive production cross section for pp→t¯t is performed at a center-of-mass energy of 7 TeV using data collected by the CMS experiment at the LHC. The analysis uses a data sample corresponding to an integrated luminosity of 36 pb−1, and is based on the final state with one isolated, high transverse momentum muon or electron, missing transverse energy, and hadronic jets. The t¯t content of the selected events ...Journal Article -

Measurement of the Wγ and Zγ inclusive cross sections in pp collisions at √s=7 TeV and limits on anomalous triple gauge boson couplings
(2014)Physical Review DMeasurements of Wγ and Zγ production in proton-proton collisions at √s=7 TeV are used to extract limits on anomalous triple gauge couplings. The results are based on data recorded by the CMS experiment at the LHC that correspond to an integrated luminosity of 5.0 fb−1. The cross sections are measured for photon transverse momenta pγT>15 GeV, and for separations between photons and final-state charged leptons in the pseudorapidity-azimuthal ...Journal Article -
Measurement of higher-order harmonic azimuthal anisotropy in PbPb collisions at √sNN=2.76 TeV
(2014)Physical Review CMeasurements are presented by the CMS Collaboration at the Large Hadron Collider (LHC) of the higher-order harmonic coefficients that describe the azimuthal anisotropy of charged particles emitted in √sNN=2.76 TeV PbPb collisions. Expressed in terms of the Fourier components of the azimuthal distribution, the n=3–6 harmonic coefficients are presented for charged particles as a function of their transverse momentum (0.3<pT<8.0GeV/c), ...Journal Article -
Search for supersymmetry in events with b-quark jets and missing transverse energy in pp collisions at 7 TeV
(2012)Physical Review DResults are presented from a search for physics beyond the standard model based on events with large missing transverse energy, at least three jets, and at least one, two, or three b-quark jets. The study is performed using a sample of proton-proton collision data collected at √s=7 TeV with the CMS detector at the LHC in 2011. The integrated luminosity of the sample is 4.98 fb−1. The observed number of events is found to be consistent ...Journal Article -
Measurement of the differential cross section for isolated prompt photon production in pp collisions at 7 TeV
(2011)Physical Review DA measurement of the differential cross section for the inclusive production of isolated prompt photons in proton-proton collisions at a center-of-mass energy of 7 TeV is presented. The data sample corresponds to an integrated luminosity of 36 pb−1 recorded by the CMS detector at the LHC. The measurement covers the pseudorapidity range |η|<2.5 and the transverse energy range 25<ET<400 GeV, corresponding to the kinematic region 0.007<xT<0.114. ...Journal Article
