Search for long-lived particles that decay into final states containing two electrons or two muons in proton-proton collisions at √s = 8 TeV
(2015)Physical Review DA search is performed for long-lived particles that decay into final states that include a pair of electrons or a pair of muons. The experimental signature is a distinctive topology consisting of a pair of charged leptons originating from a displaced secondary vertex. Events corresponding to an integrated luminosity of 19.6 (20.5) fb−1 in the electron (muon) channel were collected with the CMS detector at the CERN LHC in proton-proton ...Journal Article -
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 -
Comparison of the Z/γ ∗ + jets to γ + jets cross sections in pp collisions at √s=8 TeV
(2015)Journal of High Energy PhysicsA comparison of the differential cross sections for the processes Z/γ * + jets and photon (γ)+jets is presented. The measurements are based on data collected with the CMS detector at s√=8 TeV corresponding to an integrated luminosity of 19.7 fb−1. The differential cross sections and their ratios are presented as functions of p T. The measurements are also shown as functions of the jet multiplicity. Differential cross sections are obtained ...Journal Article -

Search for a Higgs boson in the mass range from 145 to 1000 GeV decaying to a pair of W or Z bosons
(2015)Journal of High Energy PhysicsA search for a heavy Higgs boson in the H → WW and H → ZZ decay channels is reported. The search is based upon proton-proton collision data samples corresponding to an integrated luminosity of up to 5.1 fb−1 at s√=7 TeV and up to 19.7fb−1 at s√=8 TeV, recorded by the CMS experiment at the CERN LHC. Several final states of the H → WW and H → ZZ decays are analyzed. The combined upper limit at the 95% confidence level on the product of the ...Journal Article -
Search for physics beyond the standard model in events with two leptons, jets, and missing transverse momentum in pp collisions at √s= 8 TeV
(2015)Journal of High Energy PhysicsA search is presented for physics beyond the standard model in final states with two opposite-sign same-flavor leptons, jets, and missing transverse momentum. The data sample corresponds to an integrated luminosity of 19.4 fb−1 of proton-proton collisions at s√ = 8 TeV collected with the CMS detector at the CERN LHC in 2012. The analysis focuses on searches for a kinematic edge in the invariant mass distribution of the oppositesign ...Journal Article -
Combined Measurement of the Higgs Boson Mass in pp Collisions at √s=7 and 8 TeV with the ATLAS and CMS Experiments
(2015)Physical Review LettersA measurement of the Higgs boson mass is presented based on the combined data samples of the ATLAS and CMS experiments at the CERN LHC in the H→γγ and H→ZZ→4ℓ decay channels. The results are obtained from a simultaneous fit to the reconstructed invariant mass peaks in the two channels and for the two experiments. The measured masses from the individual channels and the two experiments are found to be consistent among themselves. The ...Journal Article -
Search for a charged Higgs boson in pp collisions at √s =8 TeV
(2015)Journal of High Energy PhysicsA search for a charged Higgs boson is performed with a data sample corresponding to an integrated luminosity of 19.7 ± 0.5 fb−1 collected with the CMS detector in proton-proton collisions at s√=8,TeV. The charged Higgs boson is searched for in top quark decays for m H± < m t − m b, and in the direct production pp → t(b)H± for m H± > m t − m b. The H± → τ ± ν τ and H± → tb decay modes in the final states τ h+jets, μτ h, ℓ+jets, and ℓℓ’ (ℓ ...Journal Article -
Search for supersymmetry using razor variables in events with b-tagged jets in pp collisions at root s=8 TeV
(2015)Physical Review DAn inclusive search for supersymmetry in events with at least one b-tagged jet is performed using proton-proton collision data collected by the CMS experiment in 2012 at a center-of-mass energy of 8 TeV. The data set size corresponds to an integrated luminosity of 19.3 fb−1. The two-dimensional distribution of the razor variables R2 and MR is studied in events with and without leptons. The data are found to be consistent with the expected ...Journal Article
