Observation of the diphoton decay mode of the recently discovered Higgs boson and measurement of some of its properties are reported. The analysis uses the entire dataset collected by the CMS experiment in proton-proton collisions during the 2011 and 2012 LHC running periods. The data samples correspond to integrated luminosities of 5.1 fb −1 at √ s = 7 TeV(More)
A search for invisible decays of Higgs bosons is performed using the vector boson fusion and associated ZH production modes. In the ZH mode, the Z boson is required to decay to a pair of charged leptons or a bb quark pair. The searches use the 8 TeV pp collision dataset collected by the CMS detector at the LHC, corresponding to an integrated luminosity of(More)
Results are presented from a search for particle dark matter (DM), extra dimensions, and unparticles using events containing a jet and an imbalance in transverse momentum. The data were collected by the CMS detector in proton–proton collisions at the LHC and correspond to an integrated luminosity of 19.7 fb −1 at a centre-of-mass energy of 8 TeV. The number(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)
Searches for the direct electroweak production of supersymmetric charginos, neutralinos, and sleptons in a variety of signatures with leptons and W, Z, and Higgs bosons are presented. Results are based on a sample of proton-proton collision data collected at center-of-mass energy √ s = 8 TeV with the CMS detector in 2012, corresponding to an integrated(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)
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)
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)
A measurement of differential cross sections for the production of a pair of isolated photons in proton–proton collisions at √ s = 7 TeV is presented. The data sample corresponds to an integrated luminosity of 5.0 fb −1 collected with the CMS detector. A data-driven isolation template method is used to extract the prompt diphoton yield. The measured cross(More)
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 fits to CMS UE proton–proton (pp) data at √ s = 7 TeV and to UE proton–antiproton (pp) data from the CDF experiment at lower √ s, are used to(More)
