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 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 ...
Search for leptonic decays of W′ bosons in pp collisions at √s = 7 TeV
(Springer-Verlag, 2012-08)
A search for a new heavy gauge boson W[superscript ′] decaying to an electron or muon, plus a low mass neutrino, is presented. This study uses data corresponding to an integrated luminosity of 5.0 fb[superscript −1], ...
Search for anomalous production of multilepton events in pp collisions at √s = 7 TeV
(Springer-Verlag, 2012-06)
A search for anomalous production of events with three or more isolated leptons in pp collisions at √s = 7 TeV is presented. The data, corresponding to an integrated luminosity of 4.98 fb[superscript −1], were collected ...
Azimuthal anisotropy of charged particles at high transverse momenta in Pb-Pb collisions at √s NN=2.76TeV
(American Physical Society, 2012-07)
The azimuthal anisotropy of charged particles in Pb-Pb collisions at √sNN=2.76 TeV is measured with the CMS detector at the LHC over an extended transverse momentum (pT) range up to approximately 60 GeV/c. The data cover ...
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 new physics in events with opposite-sign leptons, jets, and missing transverse energy in pp collisions at √s = 7 TeV
(Elsevier, 2012-11)
A search is presented for physics beyond the standard model (BSM) in final states with a pair of opposite-sign isolated leptons accompanied by jets and missing transverse energy. The search uses LHC data recorded at a ...
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 ...
Observation of long-range, near-side angular correlations in pPb collisions at the LHC
(Elsevier, 2012-11)
Results on two-particle angular correlations for charged particles emitted in pPb collisions at a nucleon–nucleon center-of-mass energy of 5.02 TeV are presented. The analysis uses two million collisions collected with the ...
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 ...
