Measurement of Higgs boson production and properties in the WW decay channel with leptonic final states
(2014)Journal of High Energy PhysicsA search for the standard model Higgs boson decaying to a W-boson pair at the LHC is reported. The event sample corresponds to an integrated luminosity of 4.9 fb−1 and 19.4 fb−1 collected with the CMS detector in pp collisions at s√ = 7 and 8 TeV, respectively. The Higgs boson candidates are selected in events with two or three charged leptons. An excess of events above background is observed, consistent with the expectation from the ...Journal Article -
Measurement of the t-channel single-top-quark production cross section and of the |V tb| CKM matrix element in pp collisions at √s = 8 TeV
(2014)Journal of High Energy PhysicsMeasurements are presented of the t-channel single-top-quark production cross section in proton-proton collisions at s√ = 8 TeV. The results are based on a data sample corresponding to an integrated luminosity of 19.7 fb−1 recorded with the CMS detector at the LHC. The cross section is measured inclusively, as well as separately for top (t) and antitop (t¯), in final states with a muon or an electron. The measured inclusive t-channel cross ...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 -
Measurement of the properties of a Higgs boson in the four-lepton final state
(2014)Physical Review DThe properties of a Higgs boson candidate are measured in the H→ZZ→4ℓ decay channel, with ℓ=e, μ, using data from pp collisions corresponding to an integrated luminosity of 5.1 fb−1 at the center-of-mass energy of √s=7 TeV and 19.7 fb−1 at √s=8 TeV, recorded with the CMS detector at the LHC. The new boson is observed as a narrow resonance with a local significance of 6.8 standard deviations, a measured mass of 125.6±0.4(stat)±0.2(syst) GeV, ...Journal Article -
Measurement of the ratio of inclusive jet cross sections using the anti-kT algorithm with radius parameters R=0.5 and 0.7 in pp collisions at √s=7 TeV
(2014)Physical Review DMeasurements of the inclusive jet cross section with the anti-kT clustering algorithm are presented for two radius parameters, R=0.5 and 0.7. They are based on data from LHC proton-proton collisions at √s=7 TeV corresponding to an integrated luminosity of 5.0 fb−1 collected with the CMS detector in 2011. The ratio of these two measurements is obtained as a function of the rapidity and transverse momentum of the jets. Significant ...Journal Article -
Measurements of the t¯t charge asymmetry using the dilepton decay channel in pp collisions at √s = 7 TeV
(2014)Journal of High Energy PhysicsThe tt¯ charge asymmetry in proton-proton collisions at s√ = 7 TeV is measured using the dilepton decay channel (ee, eμ, or μμ). The data correspond to a total integrated luminosity of 5.0 fb−1, collected by the CMS experiment at the LHC. The tt and lepton charge asymmetries, defined as the differences in absolute values of the rapidities between the reconstructed top quarks and antiquarks and of the pseudorapidities between the positive ...Journal Article -
Measurement of the triple-differential cross section for photon + jets production in proton-proton collisions at √s = 7 TeV
(2014)Journal of High Energy PhysicsA measurement of the triple-differential cross section, d3σ/(dpγTdηγdηjet), in photon + jets final states using a data sample from proton-proton collisions at s√ = 7 TeV is presented. This sample corresponds to an integrated luminosity of 2.14 fb−1 collected by the CMS detector at the LHC. Photons and jets are reconstructed within a pseudorapidity range of |η| < 2.5, and are required to have transverse momenta in the range 40 < pjetT < ...Journal Article -
Search for new physics in the multijet and missing transverse momentum final state in proton-proton collisions at √s = 8 TeV
(2014)Journal of High Energy PhysicsA search for new physics is performed in multijet events with large missing transverse momentum produced in proton-proton collisions at s√ = 8 TeV using a data sample corresponding to an integrated luminosity of 19.5 fb−1 collected with the CMS detector at the LHC. The data sample is divided into three jet multiplicity categories (3-5, 6-7, and ≥8 jets), and studied further in bins of two variables: the scalar sum of jet transverse momenta ...Journal Article
