Search for Heavy Neutrinos and WR Bosons with Right-Handed Couplings in a Left-Right Symmetric Model in pp Collisions at √s=7 TeV
(2012)Physical Review LettersResults are presented from a search for heavy, right-handed muon neutrinos, Nμ, and right-handed WR bosons, which arise in the left-right symmetric extensions of the standard model. The analysis is based on a 5.0 fb−1 sample of proton-proton collisions at a center-of-mass energy of 7 TeV, collected by the CMS detector at the Large Hadron Collider. No evidence is observed for an excess of events over the standard model expectation. For ...Journal Article -
Performance of τ-lepton reconstruction and identification in CMS
(2012)Journal of InstrumentationThe 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 detector at the LHC. The τ leptons that decay into one or three charged hadrons, zero or more short-lived neutral hadrons, and a neutrino are identified using final-state particles reconstructed in the CMS tracker and ...Journal Article
