Search for Narrow Resonances in Dijet Final States at √s=8 TeV with the Novel CMS Technique of Data Scouting
(2016)Physical Review LettersA search for narrow resonances decaying into dijet final states is performed on data from proton-proton collisions at a center-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 18.8 fb−1. The data were collected with the CMS detector using a novel technique called data scouting, in which the information associated with these selected events is much reduced, permitting collection of larger data samples. This technique ...Journal Article -
Measurement of the differential cross section and charge asymmetry for inclusive pp→W±+X production at √s=8 TeV
(2016)The European Physical Journal CThe differential cross section and charge asymmetry for inclusive pp→W±+X→μ±ν+X production at √s=8TeV are measured as a function of muon pseudorapidity. The data sample corresponds to an integrated luminosity of 18.8fb−1 recorded with the CMS detector at the LHC. These results provide important constraints on the parton distribution functions of the proton in the range of the Bjorken scaling variable x from 10−3 to 10−1.Journal Article -
Measurement of the W+W- cross section in pp collisions at √s= 8 TeV and limits on anomalous gauge couplings
(2016)The European Physical Journal CA 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 19.4fb-1. The W+W− candidates are selected from events with two charged leptons, electrons or muons, and large missing transverse energy. The measured W+W− cross section is 60.1±0.9(stat)±3.2(exp)±3.1(theo)±1.6(lumi)\,pb=60.1±4.8\,pb, ...Journal Article -
ϒ(nS) polarizations versus particle multiplicity in pp collisions at √s=7 TeV
(2016)Physics Letters BThe polarizations of the ϒ(1S), ϒ(2S), and ϒ(3S) mesons are measured as a function of the charged particle multiplicity in proton–proton collisions at s=7 TeV. The measurements are performed with a dimuon data sample collected in 2011 by the CMS experiment, corresponding to an integrated luminosity of 4.9 fb−1. The results are extracted from the dimuon decay angular distributions, in two ranges of ϒ(nS) transverse momentum (10–15 and 15–35 ...Journal Article -
Transverse momentum spectra of inclusive b jets in pPb collisions at √sNN=5.02TeV
(2016)Physics Letters BWe present a measurement of b jet transverse momentum (pT) spectra in proton-lead (pPb) collisions using a dataset corresponding to about 35 nb−1 collected with the CMS detector at the LHC. Jets from b quark fragmentation are found by exploiting the long lifetime of hadrons containing a b quark through tagging methods using distributions of the secondary vertex mass and displacement. Extracted cross sections for b jets are scaled by the ...Journal Article -
Measurement of the ratio B(B0s→J/ψf0(980))/B(B0s→J/ψφ(1020)) in pp collisions at √s = 7 TeV
(2016)Physics Letters BA measurement of the ratio of the branching fractions of the Bs0 meson to J/ψf0(980) and to J/ψϕ(1020) is presented. The J/ψ, f0(980), and ϕ(1020) are observed through their decays to μ+μ−, π+π−, and K+K−, respectively. The f0 and the ϕ are identified by requiring |Mπ+π−−974 MeV|<50 MeV and |MK+K−−1020 MeV|<10 MeV. The analysis is based on a data sample of pp collisions at a centre-of-mass energy of 7 TeV, collected by the CMS experiment ...Journal Article -

Measurement of differential cross sections for Higgs boson production in the diphoton decay channel in pp collisions at √s = 8 TeV
(2016)The European Physical Journal CA measurement is presented of differential cross sections for Higgs boson (H) production in pp collisions at s√=8 TeV. The analysis exploits the H→γγ decay in data corresponding to an integrated luminosity of 19.7fb-1 collected by the CMS experiment at the LHC. The cross section is measured as a function of the kinematic properties of the diphoton system and of the associated jets. Results corrected for detector effects are compared with ...Journal Article -
