Study of high-p T charged particle suppression in PbPb compared to pp collisions at √sNN = 2.76 TeV
(Elsevier, 2012-03)
The transverse momentum spectra of charged particles have been measured in pp and PbPb collisions at √sNN=2.76 TeV by the CMS experiment at the LHC. In the transverse momentum range pT=5–10 GeV/c, the charged particle yield ...
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 ...
Performance of CMS muon reconstruction in pp collision events at √s = 7 TeV
(IOP Publishing, 2012-10)
The performance of muon reconstruction, identification, and triggering in CMS has been studied using 40 pb⁻¹ of data collected in pp collisions at √s = 7 TeV at the LHC in 2010. A few benchmark sets of selection criteria ...
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 ...
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, ...
Measurement of the Z/γ* + b-jet cross section in pp collisions at √s = 7 TeV
(Springer Nature, 2012-06)
The production of b jets in association with a Z/γ*boson is studied using proton-proton collisions delivered by the LHC at a centre-of-mass energy of 7TeV and recorded by the CMS detector. The inclusive cross section for ...
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 flavor changing neutral currents in top quark decays in pp collisions at 7 TeV
(Elsevier, 2012-12)
The results of a search for flavor changing neutral currents in top quark decays t→Zq in events with a topology compatible with the decay chain tt¯→Wb+Zq→ℓνb+ℓℓq are presented. The search is performed with a data sample ...
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. ...
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 ...
