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)

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)
A measurement is presented of differential cross sections for Higgs boson (H) production in pp collisions at √ s = 8 TeV. The analysis exploits the H → γ γ decay in data corresponding to an integrated luminosity of 19.7 fb −1 collected by the CMS experiment at the LHC. The cross section is measured as a function of the kinematic properties of the diphoton(More)
Event generator tunes obtained from underlying event and multiparton scattering measurements" (2016). Kenneth Bloom Publications. 367. Abstract New sets of parameters (" tunes ") for the underlying-event (UE) modelling of the pythia8, pythia6 and herwig++ Monte Carlo event generators are constructed using different parton distribution functions. Combined(More)
The production cross section of a W boson in association with two b jets is measured using a sample of proton–proton collisions at √ s = 8 TeV collected by the CMS experiment at the CERN LHC. The data sample corresponds to an integrated luminosity of 19.8 fb −1. The W bosons are reconstructed via their leptonic decays, W → ν, where = μ or e. The fiducial(More)
Search for new physics in same-sign dilepton events in proton–proton collisions at √ s = 13 TeV Abstract A search for new physics is performed using events with two isolated same-sign leptons, two or more jets, and missing transverse momentum. The results are based on a sample of proton–proton collisions at a center-of-mass energy of 13 TeV recorded with(More)
Forward–backward asymmetry of Drell–Yan lepton pairs in pp collisions at √ s = 8 TeV Abstract A measurement of the forward–backward asymmetry A FB of oppositely charged lepton pairs (μμ and ee) produced via Z/γ * boson exchange in pp collisions at √ s = 8 TeV is presented. The data sample corresponds to an integrated luminosity of 19.7 fb −1 collected with(More)
A search is presented for narrow heavy resonances X decaying into pairs of Higgs bosons ([Formula: see text]) in proton-proton collisions collected by the CMS experiment at the LHC at [Formula: see text]. The data correspond to an integrated luminosity of 19.7[Formula: see text]. The search considers [Formula: see text] resonances with masses between 1 and(More)
The top quark pair production cross section is measured for the first time in proton-proton collisions at sqrt[s]=13  TeV by the CMS experiment at the CERN LHC, using data corresponding to an integrated luminosity of 43  pb^{-1}. The measurement is performed by analyzing events with at least one electron and one muon of opposite charge, and at least two(More)
A measurement of the W boson pair production cross section in proton-proton collisions at √ s = 8 TeV is presented. The data collected with the CMS detector at the LHC correspond to an integrated luminosity of 19.4 fb −1. The W + W − candidates are selected from events with two charged leptons, electrons or muons, and large missing transverse energy. The(More)
