Measurement of top quark–antiquark pair production in association with a W or Z boson in pp collisions at √s = 8 TeV
A measurement of the cross section for the production of top quark–antiquark pairs ( t [bar over t]) in association with a vector boson V (W or Z) in proton-proton collisions at √s=8 TeV is presented. The results are based ...
Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV
Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse ...
Measurement of the Wγ and Zγ< Inclusive Cross Sections in pp Collisions at √s = 7 TeV and Limits on Anomalous Triple Gauge Boson Couplings
(American Physical Society, 2014-05)
Measurements of Wγ and Zγ production in proton-proton collisions at √s = 7 TeV are used to extract limits on anomalous triple gauge couplings. The results are based on data recorded by the CMS experiment at the LHC that ...
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 ...
Measurement of Prompt ψ(2S) to J/ψ Yield Ratios in Pb-Pb and p-p Collisions at √s[subscript NN] = 2.76 TeV
(American Physical Society, 2014-12)
The ratio between the prompt ψ(2S) and J/ψ yields, reconstructed via their decays into μ[superscript +]μ[superscript -], is measured in Pb-Pb and p-p collisions at √s[subscript NN] = 2.76 TeV. The analysis is based on ...
Study of hadronic event-shape variables in multijet final states in pp collisions at √s = 7 TeV
(Springer-Verlag/International School for Advanced Studies (SISSA), 2014-10)
Event-shape variables, which are sensitive to perturbative and nonperturbative aspects of quantum chromodynamic (QCD) interactions, are studied in multijet events recorded in proton-proton collisions at √s = 7 TeV. Events ...
Erratum: Search for the associated production of the Higgs boson with a top-quark pair
(Springer Berlin Heidelberg, 2014-10)
The x-axis of figure 2, lower left panel (“Lepton + ≥ 6 jets + 2 b-tags”) should be replaced with “3rd highest CSV output”.
Measurement of the pp → ZZ production cross section and constraints on anomalous triple gauge couplings in four-lepton final states at √s = 8 TeV
A measurement of the inclusive ZZ production cross section and constraints on anomalous triple gauge couplings in proton–proton collisions at √s = 8 TeV are presented. The analysis is based on a data sample, corresponding ...
Observation of the diphoton decay of the Higgs boson and measurement of its properties
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 ...
Search for heavy neutrinos and W bosons with right-handed couplings in proton–proton collisions at √s = 8 TeV
A search for heavy, right-handed neutrinos, Nℓ ( ℓ=e,μ ), and right-handed W[subscript R] bosons, which arise in the left-right symmetric extensions of the standard model, has been performed by the CMS experiment. The ...
