Measurement of prompt J/ψ pair production in pp collisions at s √s = 7 Tev
(Springer-Verlag Berlin Heidelberg, 2014-09)
Production of prompt J/ψ meson pairs in proton-proton collisions at s√ = 7 TeV is measured with the CMS experiment at the LHC in a data sample corresponding to an integrated luminosity of about 4.7 fb[superscript −1]. The ...
Studies of azimuthal dihadron correlations in ultra-central PbPb collisions at √s[subscript NN] =2.76 TeV
(Springer-Verlag, 2014-02)
Azimuthal dihadron correlations of charged particles have been measured in PbPb collisions at √s[subscript NN] = 2.76TeV by the CMS collaboration, using data from the 2011 LHC heavy-ion run. The data set includes a sample ...
Search for new physics in events with same-sign dileptons and jets in pp collisions at √s = 8 TeV
(Springer-Verlag, 2014-01)
A search for new physics is performed based on events with jets and a pair of isolated, same-sign leptons. The results are obtained using a sample of proton-proton collision data collected by the CMS experiment at a ...
Measurement of the production cross sections for a Z boson and one or more b jets in pp collisions at √s = 7 TeV
(Springer-Verlag, 2014-06)
The production of a Z boson, decaying into two leptons and produced in association with one or more b jets, is studied using proton-proton collisions delivered by the LHC at a centre-of-mass energy of 7 TeV. The data were ...
Search for invisible decays of Higgs bosons in the vector boson fusion and associated ZH production modes
(Springer-Verlag, 2014-08)
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 b[bar over b] ...
Measurement of the t[bar over t] production cross section in pp collisions at √s = 8 TeV in dilepton final states containing one τ lepton
(Elsevier, 2014-10)
The top-quark pair production cross section is measured in final states with one electron or muon and one hadronically decaying τ lepton from the process t[bar over t] → (ℓν[subscript ℓ])(τν[subscript τ])b[bar over b], ...
Search for massive resonances in dijet systems containing jets tagged as W or Z boson decays in pp collisions at √s = 8 TeV
(Springer-Verlag, 2014-08)
A search is reported for massive resonances decaying into a quark and a vector boson (W or Z), or two vector bosons (WW, WZ, or ZZ). The analysis is performed on an inclusive sample of multijet events corresponding to an ...
Search for anomalous production of events with three or more leptons in pp collisions at √s = 8 TeV
(American Physical Society, 2014-08)
A search for physics beyond the standard model in events with at least three leptons is presented. The data sample, corresponding to an integrated luminosity of 19.5 fb[superscript −1] of proton-proton collisions with ...
Measurement of the Muon Charge Asymmetry in Inclusive pp → W + X Production at √s = 7 TeV and an Improved Determination of Light Parton Distribution Functions
(American Physical Society, 2014-08)
Measurements of the muon charge asymmetry in inclusive pp → W + X production at √s = 7 TeV are presented. The data sample corresponds to an integrated luminosity of 4.7 fb[superscript −1] recorded with the CMS detector ...
Search for new physics in the multijet and missing transverse momentum final state in proton-proton collisions at √s = 8 TeV
(Springer-Verlag, 2014-06)
A search for new physics is performed in multijet events with large missing transverse momentum produced in proton-proton collisions at √s = 8 TeV using a data sample corresponding to an integrated luminosity of 19.5 ...
