Measurement of the charge asymmetry in top-quark pair production in proton–proton collisions at √s = 7 TeV
(Elsevier, 2012-02)
The difference in angular distributions between top quarks and antiquarks, commonly referred to as the charge asymmetry, is measured in pp collisions at the LHC with the CMS experiment. The data sample corresponds to an ...
Measurement of isolated photon production in pp and PbPb collisions at √s[subscript NN] = 2.76 TeV
(Elsevier, 2012-03)
Isolated photon production is measured in proton–proton and lead–lead collisions at nucleon–nucleon centre-of-mass energies of 2.76 TeV in the pseudorapidity range |η|<1.44 and transverse energies E[subscript T] between ...
Inclusive and differential measurements of the t[bar over t] charge asymmetry in proton-proton collisions at √s = 7 TeV
(Elsevier, 2012-09)
The t[bar over t] charge asymmetry is measured in events containing a charged lepton (electron or muon) and at least four jets, one of which is identified as originating from b-quark hadronization. The analyzed dataset ...
Search for a W′ or Techni-ρ Decaying into WZ in pp Collisions at √s=7 TeV
(American Physical Society, 2012-10)
A search is performed in pp collisions at √s=7 TeV for exotic particles decaying via WZ to final states with electrons and muons. The data sample corresponds to an integrated luminosity of approximately 5 fb[superscript ...
Search for supersymmetry in events with b-quark jets and missing transverse energy in pp collisions at 7 TeV
(American Physical Society, 2012-10)
Results are presented from a search for physics beyond the standard model based on events with large missing transverse energy, at least three jets, and at least one, two, or three b-quark jets. The study is performed using ...
Measurement of the production cross section for pairs of isolated photons in pp collisions at √s = 7 TeV
(Springer-Verlag, 2012-01)
The integrated and differential cross sections for the production of pairs of isolated photons is measured in proton-proton collisions at a centre-of-mass energy of 7 TeV with the CMS detector at the LHC. A data sample ...
Search for a Narrow, Spin-2 Resonance Decaying to a Pair of Z Bosons in the q[bar over q]ℓ[superscript +]ℓ[superscript −] Final State
(Elsevier, 2012-12)
Results are presented from a search for a narrow, spin-2 resonance decaying into a pair of Z bosons, with one Z-boson decaying into leptons (e[superscript +]e[superscript −] or μ[superscript +]μ[superscript −]) and the ...
Search for Heavy Majorana Neutrinos in μ[superscript ±]μ[superscript ±] + just and e[superscript ±]e[superscript ±] + jets events in pp collisions at √s = 7 TeV
(Elsevier, 2012-09)
A search is performed for heavy Majorana neutrinos (N) using an event signature defined by two same-sign charged leptons of the same flavour and two jets. The data correspond to an integrated luminosity of 4.98 fb[superscript ...
Combined results of searches for the standard model Higgs boson in pp collisions at √s = 7 TeV
(Elsevier, 2012-02)
Combined results are reported from searches for the standard model Higgs boson in proton–proton collisions at √s = 7 TeV in five Higgs boson decay modes: γγ, bb, ττ , WW, and ZZ. The explored Higgs boson mass range is ...
Search for the Standard Model Higgs Boson Decaying to W[superscript +]W[superscript -] in the Fully Leptonic Final State in pp Collisions at √s = 7 TeV
(Elsevier, 2012-03)
A search for the standard model Higgs boson decaying to W[superscript +]W[superscript −] in pp collisions at √s = 7 TeV is reported. The data are collected at the LHC with the CMS detector, and correspond to an integrated ...
