Study of W boson production in PbPb and pp collisions at root s(NN)=2.76 TeV
A measurement is presented of W-boson production in PbPb collisions carried out at a nucleon-nucleon (NN) centre-of-mass energy root S-NN of 2.76 TeV at the LHC using the CMS detector. In data corresponding to an integrated ...
Inclusive and differential measurements of the t(t)over-bar charge asymmetry in proton-proton collisions root s=7 TeV
The t (t) over bar charge asymmetry is measured in events containing a charged lepton (electron or muon) and at least four jets, one of which is identified as originating from b-quark hadronization. The analyzed dataset ...
Study of the inclusive production of charged pions, kaons, and protons in pp collisions at root s=0.9, 2.76, and 7 TeV
(Springer Science+Business Media, 2012-10)
Spectra of identified charged hadrons are measured in pp collisions at the LHC for root s = 0.9, 2.76, and 7 TeV. Charged pions, kaons, and protons in the transverse-momentum range p(T) approximate to 0.1-1.7 GeV/c and for ...
Observation of a new boson at a mass of 125 GeV with the CMS experiment at the LHC
Results are presented from searches for the standard model Higgs boson in proton-proton collisions at root s = 7 and 8 TeV in the Compact Muon Solenoid experiment at the LHC, using data samples corresponding to integrated ...
Search for a light pseudoscalar higgs boson in the dimuon decay channel in pp collisions at root s=7 TeV
(American Physical Society, 2012-09-21)
The dimuon invariant mass spectrum is searched in the range between 5.5 and 14 GeV for a light pseudoscalar Higgs boson a, predicted in a number of new physics models, including the next-to-minimal supersymmetric standard ...
Search for heavy Majorana neutrinos in μ±μ±+jets and e±e±+jets events in pp collisions at =7 TeV
A search is performed for heavy Majorana neutrinos (N) using an event signature defined by two same-sign charged leptons of the same flavour and two jets. The data correspond to an integrated luminosity of 4.98 fb−1 of pp ...
Search for heavy lepton partners of neutrinos in proton-proton collisions in the context of the type III seesaw mechanism
A search is presented in proton-proton collisions at root s = 7 TeV for fermionic triplet states expected in type Ill seesaw models. The search is performed using final states with three isolated charged leptons and an ...
Search for three-jet resonances in pp collisions at root s=7 TeV
Results are reported from a search for the production of three-jet resonances in pp collisions at a center-of-mass energy root s = 7 TeV. The study uses the data sample collected by the CMS experiment at the LHC in 2011, ...
