Search for a W′ or Techni-ρ Decaying into WZ in pp Collisions at √s=7 TeV
(2012)Physical Review LettersA 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−1. No significant excess is observed in the data above the expected standard model background. Upper bounds at 95% confidence level are set on the production cross section of the W′ boson described by the sequential standard model ...Journal Article -
Search for supersymmetry in events with b-quark jets and missing transverse energy in pp collisions at 7 TeV
(2012)Physical Review DResults are presented from a search for physics beyond the standard model based on events with large missing transverse energy, at least three jets, and at least one, two, or three b-quark jets. The study is performed using a sample of proton-proton collision data collected at √s=7 TeV with the CMS detector at the LHC in 2011. The integrated luminosity of the sample is 4.98 fb−1. The observed number of events is found to be consistent ...Journal Article -
Search for dark matter and large extra dimensions in monojet events in pp collisions at √s= 7 TeV
(2012)Journal of High Energy PhysicsA search has been made for events containing an energetic jet and an imbalance in transverse momentum using a data sample of pp collisions at a center-of-mass energy of 7 TeV. This signature is common to both dark matter and extra dimensions models. The data were collected by the CMS detector at the LHC and correspond to an integrated luminosity of 5.0 fb−1. The number of observed events is consistent with the standard model expectation. ...Journal Article -
Search for pair production of first- and second-generation scalar leptoquarks in pp collisions at √s=7 TeV
(2012)Physical Review DResults are presented from a search for the pair production of first- and second-generation scalar leptoquarks in proton-proton collisions at √s=7 TeV. The data sample corresponds to an integrated luminosity of 5.0 fb−1, collected by the CMS detector at the LHC. The search signatures involve either two charged leptons of the same flavor (electrons or muons) and at least two jets or a single charged lepton (electron or muon), missing ...Journal Article -
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
