Measurement of inclusive W and Z boson production cross sections in pp collisions at s =8TeV
(2014-05-14)
A measurement of total and fiducial inclusive W and Z boson production cross sections in pp collisions at s=8TeV is presented. Electron and muon final states are analyzed in a data sample collected with the CMS detector ...
Search for top squark and higgsino production using diphoton higgs boson decays
(2014-04-25)
Results are presented of a search for a "natural" supersymmetry scenario with gauge mediated symmetry breaking. It is assumed that only the supersymmetric partners of the top quark (the top squark) and the Higgs boson ...
Measurement of the Wγ and Zγ inclusive cross sections in pp collisions at s =7 TeV and limits on anomalous triple gauge boson couplings
(2014-05-13)
Measurements of Wγ and Zγ production in proton-proton collisions at s=7TeV are used to extract limits on anomalous triple gauge couplings. The results are based on data recorded by the CMS experiment at the LHC that ...
Search for new physics in events with same-sign dileptons and jets in pp collisions at √s = 8 TeV
(2014-01-29)
A search for new physics is performed based on events with jets and a pair of isolated, same-sign leptons. The results are obtained using a sample of proton-proton collision data collected by the CMS experiment at a ...
Search for flavor-changing neutral currents in top-quark decays t →zq in pp collisions at s =8TeV
(2014-05-02)
A search for flavor-changing neutral currents in top-quark decays t→Zq is performed in events produced from the decay chain tt̄→Zq+Wb, where both vector bosons decay leptonically, producing a final state with three leptons ...
Study of double parton scattering using W + 2-jet events in proton-proton collisions at √s = 7 TeV
(2014-03-05)
Double parton scattering is investigated in proton-proton collisions at s√ = 7 TeV where the final state includes a W boson, which decays into a muon and a neutrino, and two jets. The data sample corresponds to an integrated ...
Measurement of the production cross sections for a Z boson and one or more b jets in pp collisions at √s = 7 TeV
(2014-06-12)
The production of a Z boson, decaying into two leptons and produced in association with one or more b jets, is studied using proton-proton collisions delivered by the LHC at a centre-of-mass energy of 7 TeV. The data were ...
Observation of the associated production of a single top quark -and a W boson in pp collisions at s =8TeV
(2014-06-09)
The first observation of the associated production of a single top quark and a W boson is presented. The analysis is based on a data set corresponding to an integrated luminosity of 12.2fb-1 of proton-proton collisions at ...
Measurement of higher-order harmonic azimuthal anisotropy in PbPb collisions at s NN =2.76 TeV
(2014-04-11)
Measurements are presented by the CMS Collaboration at the Large Hadron Collider (LHC) of the higher-order harmonic coefficients that describe the azimuthal anisotropy of charged particles emitted in sNN=2.76 TeV PbPb ...
Search for new physics in the multijet and missing transverse momentum final state in proton-proton collisions at √s = 8 TeV
(2014-06-10)
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 ...
