Search for supersymmetry in events with a photon, a lepton, and missing transverse momentum in pp collisions at √s=8 TeV
(2016)Physics Letters BA search for supersymmetry involving events with at least one photon, one electron or muon, and large missing transverse momentum has been performed by the CMS experiment. The data sample corresponds to an integrated luminosity of 19.7 fb-1 of pp collisions at s=8 TeV, produced at the CERN LHC. No excess of events is observed beyond expectations from standard model processes. The result of the search is interpreted in the context of a ...Journal Article -
Measurement of the CP-violating weak phase ϕs and the decay width difference ΔΓs using the B0s→J/ψϕ(1020) decay channel in pp collisions at √s=8TeV
(2016)Physics Letters BThe CP-violating weak phase φs of the Bs0 meson and the decay width difference δΓs of the Bs0 light and heavy mass eigenstates are measured with the CMS detector at the LHC using a data sample of Bs0→J/ψφ(1020)→μ+μ-K+K- decays. The analysed data set corresponds to an integrated luminosity of 19.7fb-1 collected in pp collisions at a centre-of-mass energy of 8TeV. A total of 49 200 reconstructed Bs0 decays are used to extract the values of ...Journal Article -
Search for pair-produced vectorlike B quarks in proton-proton collisions at √s=8 TeV
(2016)Physical Review DA search for the production of a heavy B quark, having electric charge −1/3 and vector couplings to W, Z, and H bosons, is carried out using proton-proton collision data recorded at the CERN LHC by the CMS experiment, corresponding to an integrated luminosity of 19.7 fb−1. The B quark is assumed to be pair produced and to decay in one of three ways: to tW, bZ, or bH. The search is carried out in final states with one, two, and more than ...Journal Article -
Search for the associated production of a Higgs boson with a single top quark in proton-proton collisions at √s= 8 TeV
(2016)Journal of High Energy PhysicsThis paper presents the search for the production of a Higgs boson in association with a single top quark (tHq), using data collected in proton-proton collisions at a center-of-mass energy of 8 TeV corresponding to an integrated luminosity of 19.7 fb−1. The search exploits a variety of Higgs boson decay modes resulting in final states with photons, bottom quarks, and multiple charged leptons, including tau leptons, and employs a variety ...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 the inclusive jet cross section in pp collisions at √s=2.76TeV
(2016)The European Physical Journal CThe double-differential inclusive jet cross section is measured as a function of jet transverse momentum pTand absolute rapidity |y|, using proton-proton collision data collected with the CMS experiment at the LHC, at a center-of-mass energy of s√=2.76TeV and corresponding to an integrated luminosity of 5.43pb−1. Jets are reconstructed within the pTrange of 74 to 592GeVand the rapidity range |y|<3.0. The reconstructed jet spectrum is ...Journal Article -
Measurement of the top quark mass using charged particles in pp collisions at √s=8 TeV
(2016)Physical Review DA novel technique for measuring the mass of the top quark that uses only the kinematic properties of its charged decay products is presented. Top quark pair events with final states with one or two charged leptons and hadronic jets are selected from the data set of 8 TeV proton-proton collisions, corresponding to an integrated luminosity of 19.7 fb−1. By reconstructing secondary vertices inside the selected jets and computing the invariant ...Journal Article -
Search for supersymmetry in pp collisions at √s=8 TeV in final states with boosted W bosons and b jets using razor variables
(2016)Physical Review DA search for supersymmetry in hadronic final states with highly boosted W bosons and b jets is presented, focusing on compressed scenarios. The search is performed using proton-proton collision data at a center-of-mass energy of 8 TeV, collected by the CMS experiment at the LHC, corresponding to an integrated luminosity of 19.7 fb−1. Events containing candidates for hadronic decays of boosted W bosons are identified using jet substructure ...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
