Performance of τ-lepton reconstruction and identification in CMS
(IOP Publishing, 2012-01-01)
The performance of τ-lepton reconstruction and identification algorithms is studied using a data sample of proton-proton collisions at s = 7 TeV, corresponding to an integrated luminosity of 36 pb-1 collected with the CMS ...
Search for the standard model Higgs boson decaying into two photons in pp collisions at √s = 7 TeV
(Elsevier B.V., 2012-04)
A search for a Higgs boson decaying into two photons is described. The analysis is performed using a dataset recorded by the CMS experiment at the LHC from pp collisions at a center-of-mass energy of 7 TeV, which corresponds ...
Search for charge-asymmetric production of W' bosons in t[bar over t] + jet events from pp collisions at √s = 7 TeV
(Elsevier, 2012-09)
A search is presented for charge-asymmetric production of a W′ boson that has been proposed to accommodate the forward–backward asymmetry observed in the production of top–antitop quark pairs at the Tevatron. The new heavy ...
Measurement of the tt̅ production cross section in pp collisions at √s=7 TeV in dilepton final states containing a τ
(American Physical Society, 2012-06)
The top quark pair production cross section is measured in dilepton events with one electron or muon, and one hadronically decaying τ lepton from the decay tt̅ →(ℓν[subscript ℓ])(τ[subscript h]ν[subscript τ])bb̅ , (ℓ=e,μ). ...
Search for a W′ boson decaying to a bottom quark and a top quark in pp collisions at √s = 7 TeV
(Elsevier, 2012-12)
Results are presented from a search for a W′ boson using a dataset corresponding to 5.0 fb[superscript −1] of integrated luminosity collected during 2011 by the CMS experiment at the LHC in pp collisions at √s=7 TeV. The ...
Observation of a new boson at a mass of 125 GeV with the CMS experiment at the LHC
(Elsevier, 2012-08)
Results are presented from searches for the standard model Higgs boson in proton–proton collisions at √s = 7 and 8 TeV in the Compact Muon Solenoid experiment at the LHC, using data samples corresponding to integrated ...
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 ...
Ratios of dijet production cross sections as a function of the absolute difference in rapidity between jets in proton–proton collisions at √s = 7 TeV
(Springer-Verlag, 2012-11)
A study of dijet production in proton–proton collisions was performed at √s = 7 TeV for jets with pT > 35 GeV and |y| < 4.7 using data collected with the CMS detector at the LHC in 2010. Events with at least one pair of ...
Search for Heavy Neutrinos and WR Bosons with Right-Handed Couplings in a Left-Right Symmetric Model in pp Collisions at √s=7 TeV
(American Physical Society, 2012-12)
Results are presented from a search for heavy, right-handed muon neutrinos, N[subscript μ], and right-handed WR bosons, which arise in the left-right symmetric extensions of the standard model. The analysis is based on a ...
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 ...
