Centrality dependence of dihadron correlations and azimuthal anisotropy harmonics in Pb collisions at √sNN = 2.76 TeV
(Springer-Verlag, 2012-05)
Measurements from the CMS experiment at the LHC of dihadron correlations for charged particles produced in PbPb collisions at a nucleon–nucleon centre-of-mass energy of 2.76 TeV are presented. The results are reported as ...
Search for Supersymmetry in Events with Photons and Low Missing Transverse Energy in pp Collisions at √s = 7 TeV
(Elsevier, 2012-12)
Many models of new physics, including versions of supersymmetry (SUSY), predict production of events with low missing transverse energy, electroweak gauge bosons, and many energetic final-state particles. The stealth SUSY ...
Search for heavy lepton partners of neutrinos in proton–proton collisions in the context of the type III seesaw mechanism
(Elsevier, 2012-10)
A search is presented in proton–proton collisions at √s = 7 TeV for fermionic triplet states expected in type III seesaw models. The search is performed using final states with three isolated charged leptons and an imbalance ...
Search for a W′ or Techni-ρ Decaying into WZ in pp Collisions at √s=7 TeV
(American Physical Society, 2012-10)
A search is performed in pp collisions at √s=7 TeV for exotic particles decaying via WZ to final states with electrons and muons. The data sample corresponds to an integrated luminosity of approximately 5 fb[superscript ...
Measurement of the Λb cross section and the [over bar]Λ[subscript b] ratio with J/ψΛ decays in pp collisions at √s = 7 TeV
(Elsevier B.V., 2012-08)
The Λb differential production cross section and the cross section ratio σ(Λ¯b)/σ(Λb) are measured as functions of transverse momentum pΛ¯b[over]T and rapidity |yΛb| in pp collisions at √s = 7 TeV using data collected by ...
Measurement of isolated photon production in pp and PbPb collisions at √s[subscript NN] = 2.76 TeV
(Elsevier, 2012-03)
Isolated photon production is measured in proton–proton and lead–lead collisions at nucleon–nucleon centre-of-mass energies of 2.76 TeV in the pseudorapidity range |η|<1.44 and transverse energies E[subscript T] between ...
Forward energy flow, central charged-particle multiplicities, and pseudorapidity gaps in W and Z boson events from pp collisions at √s = 7 TeV
(Springer-Verlag, 2012-01)
A study of forward energy flow and central charged-particle multiplicity in events with W and Z bosons decaying into leptons is presented. The analysis uses a sample of 7 TeV pp collisions, corresponding to an integrated ...
Exclusive γγ → μ⁺μ⁻ production in proton-proton collisions at √s = 7 TeV
(Springer Berlin Heidelberg, 2012-01)
A measurement of the exclusive two-photon production of muon pairs in proton-proton collisions at √s = 7 TeV, pp → pμ⁺μ⁻ p, is reported using data corresponding to an integrated luminosity of 40 pb⁻¹. For muon pairs with ...
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 ...
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], ...
