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 ...
Measurement of the rapidity and transverse momentum distributions of Z bosons in pp collisions at √(s)=7 TeV
(American Physical Society, 2012-02)
Measurements of the normalized rapidity (y) and transverse-momentum (q[subscript T]) distributions of Drell–Yan muon and electron pairs in the Z-boson mass region (60<M[subscript ℓℓ]<120 GeV) are reported. The results are ...
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 mass difference between top and antitop quarks
(Springer-Verlag, 2012-06)
A measurement of the mass difference between the top and the antitop quark (Δm [subscript t] = m [subscript t] − m[¯ over t] ) is performed using events with a muon or an electron and at least four jets in the final state. ...
Measurement of the relative prompt production rate of χ[subscript c2] and χ[subscript c1] in pp collisions at √s = 7TeV
(Springer-Verlag, 2012-11)
A measurement is presented of the relative prompt production rate of χ[subscript c2] and χ[subscript c1] with 4.6 fb[superscript −1] of data collected by the CMS experiment at the LHC in pp collisions at √s = 7 TeV. The ...
Search for physics beyond the standard model in events with a Z boson, jets, and missing transverse energy in pp collisions at √s =7 TeV
(Elsevier B.V., 2012-09)
A search is presented for physics beyond the standard model (BSM) in events with a Z boson, jets, and missing transverse energy (Emiss[over]T) This signature is motivated by BSM physics scenarios, including supersymmetry. ...
Search for pair produced fourth-generation up-type quarks in pp collisions at √s = 7 TeV with a lepton in the final state
(Elsevier, 2012-10)
The results of a search for the pair production of a fourth-generation up-type quark (t′) in proton–proton collisions at √s = 7 TeV are presented, using data corresponding to an integrated luminosity of about 5.0 ...
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 ...
Measurement of the underlying event in the Drell–Yan process in proton–proton collisions at √s = 7 TeV
(Springer-Verlag, 2012-09)
A measurement of the underlying event (UE) activity in proton–proton collisions at a center-of-mass energy of 7 TeV is performed using Drell–Yan events in a data sample corresponding to an integrated luminosity of 2.2 ...
