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 -
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 -
Study of B Meson Production in p+Pb Collisions at √sNN = 5.02 TeV Using Exclusive Hadronic Decays
(2016)Physical Review LettersThe production cross sections of the B+, B0, and B0s mesons, and of their charge conjugates, are measured via exclusive hadronic decays in p+Pb collisions at the center-of-mass energy √sNN=5.02 TeV with the CMS detector at the CERN LHC. The data set used for this analysis corresponds to an integrated luminosity of 34.6 nb−1. The production cross sections are measured in the transverse momentum range between 10 and 60 GeV/c. No significant ...Journal Article -
A search for pair production of new light bosons decaying into muons
(2016)Physics Letters BA search for the pair production of new light bosons, each decaying into a pair of muons, is performed with the CMS experiment at the LHC, using a dataset corresponding to an integrated luminosity of 20.7 fb-1 collected in proton–proton collisions at center-of-mass energy of √s 0 8TeV. No excess is observed in the data relative to standard model background expectation and a model independent upper limit on the product of the cross section, ...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 -
Search for a low-mass pseudoscalar Higgs boson produced in association with a bb pair in pp collisions at √s=8 TeV
(2016)Physics Letters BA search is reported for a light pseudoscalar Higgs boson decaying to a pair of τ leptons, produced in association with a bb‾ pair, in the context of two-Higgs-doublet models. The results are based on pp collision data at a centre-of-mass energy of 8 TeV collected by the CMS experiment at the LHC and corresponding to an integrated luminosity of 19.7 fb−1. Pseudoscalar boson masses between 25 and 80 GeV are probed. No evidence for a ...Journal Article -

(2016)Physics Letters BThe inelastic hadronic cross section in proton–lead collisions at a centre-of-mass energy per nucleon pair of 5.02 TeV is measured with the CMS detector at the LHC. The data sample, corresponding to an integrated luminosity of L=12.6±0.4 nb−1, has been collected with an unbiased trigger for inclusive particle production. The cross section is obtained from the measured number of proton–lead collisions with hadronic activity produced in the ...Journal Article -
Search for neutral MSSM Higgs bosons decaying to μ+μ− in pp collisions at √s = 7 and 8 TeV
(2016)Physics Letters BA search for neutral Higgs bosons predicted in the minimal supersymmetric standard model (MSSM) for μ+μ- decay channels is presented.

The search is sensitive to Higgs bosons produced either through the gluon fusion process or ...Journal Article -
Search for W ' decaying to tau lepton and neutrino in proton-proton collisions at √s=8 TeV
(2016)Physics Letters BThe first search for a heavy charged vector boson in the final state with a tau lepton and a neutrino is reported, using 19.7 fb-1 of LHC data at s=8 TeV. A signal would appear as an excess of events with high transverse mass, where the standard model background is low. No excess is observed. Limits are set on a model in which the W' decays preferentially to fermions of the third generation. These results substantially extend previous ...Journal Article
