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 new physics in events with same-sign dileptons and b-tagged jets in pp collisions at √s = 7 TeV
(Springer-Verlag, 2012-08)
A search for new physics is performed using isolated same-sign dileptons with at least two b-quark jets in the final state. Results are based on a 4.98 fb[superscript −1] sample of proton-proton collisions at a centre-of-mass ...
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 ...
Study of W boson production in PbPb and pp collisions at √s[subscript NN] = 2.76 TeV
(Elsevier, 2012-07)
A measurement is presented of W-boson production in PbPb collisions carried out at a nucleon–nucleon (NN) centre-of-mass energy √s[subscript NN] = 2.76 TeV at the LHC using the CMS detector. In data corresponding to an ...
Search for anomalous t[bar over t] production in the highly-boosted all-hadronic final state
(Springer-Verlag, 2012-09)
A search is presented for a massive particle, generically referred to as a Z′, decaying into a t[bar over t] pair. The search focuses on Z[superscript ′] resonances that are sufficiently massive to produce highly Lorentz-boosted ...
Search for three-jet resonances in pp collisions at √s = 7 TeV
(Elsevier, 2012-10)
Results are reported from a search for the production of three-jet resonances in pp collisions at a center-of-mass energy √s = 7 TeV. The study uses the data sample collected by the CMS experiment at the LHC in 2011, ...
Search for the standard model Higgs boson decaying to bottom quarks in pp collisions at √s = 7 TeV
(Elsevier, 2012-03)
A search for the standard model Higgs boson (H) decaying to b[bar over b] when produced in association with weak vector bosons (V) is reported for the following modes: W(μν)H, W(eν)H, Z(μμ)H, Z(ee)H and Z(νν)H. The search ...
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 ...
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 ...
Study of the Dijet Mass Spectrum in pp→W+jets Events at √s=7 TeV
(American Physical Society, 2012-12)
We report an investigation of the invariant mass spectrum of the two jets with highest transverse momentum in pp→W+2-jet and W+3-jet events to look for resonant enhancement. The data sample corresponds to an integrated ...
