Inclusive search for a vector-like T quark with charge 2/3 in pp collisions at √s=8 TeV
A search is performed for a massive new vector-like quark T, with charge 2 3 , that is pair produced together with its antiparticle in proton–proton collisions. The data were collected by the CMS experiment at the Large ...
Search for W′→tb decays in the lepton + jets final state in pp collisions at √s = 8 TeV
Results are presented from a search for the production of a heavy gauge boson W′ decaying into a top and a bottom quark, using a data set collected by the CMS experiment at √s = 8 TeV and corresponding to an integrated ...

Search for new physics in the multijet and missing transverse momentum final state in proton-proton collisions at √s = 8 TeV
A search for new physics is performed in multijet events with large missing transverse momentum produced in proton-proton collisions at √s = 8 TeV using a data sample corresponding to an integrated luminosity of 19.5 fb−1 ...
Measurement of the tt¯ production cross section in the dilepton channel in pp collisions at √s = 8 TeV
The top-antitop quark ( tt¯) production cross section is measured in proton-proton collisions at √s = 8 TeV with the CMS experiment at the LHC, using a data sample corresponding to an integrated luminosity of 5.3 fb−1. ...
Search for supersymmetry in pp collisions at √s = 8 TeV in events with a single lepton, large jet multiplicity, and multiple b jets
Results are reported from a search for supersymmetry in pp collisions at a center-of-mass energy of 8 TeV, based on events with a single isolated lepton (electron or muon) and multiple jets, at least two of which are ...
Measurement of the hadronic activity in events with a Z and two jets and extraction of the cross section for the electroweak production of a Z with two jets in pp collisions at √s = 7 TeV
The first measurement of the electroweak production cross section of a Z boson with two jets (Zjj) in pp collisions at √s 7 TeV is presented, based on a data sample recorded by the CMS experiment at the LHC with an integrated ...
Studies of azimuthal dihadron correlations in ultra-central PbPb collisions at √sNN =2.76 TeV
Azimuthal dihadron correlations of charged particles have been measured in PbPb collisions at √sNN = 2.76TeV by the CMS collaboration, using data from the 2011 LHC heavy-ion run. The data set includes a sample of ultra-central ...
Observation of a peaking structure in the J/ψφ mass spectrum from B±→J/ψφK± decays
A peaking structure in the J/ψφ mass spectrum near threshold is observed in B± → J/ψφK± decays, produced in pp collisions at √s = 7 TeV collected with the CMS detector at the LHC. The data sample, selected on the basis ...
Measurement of the cross section and angular correlations for associated production of a Z boson with b hadrons in pp collisions at √s = 7 TeV
A study of proton-proton collisions in which two b hadrons are produced in association with a Z boson is reported. The collisions were recorded at a centre-of-mass energy of 7 TeV with the CMS detector at the LHC, for an ...
