Measurement of the t[bar over t] Production Cross Section in the All-Jet Final State in Pp Collisions at √s =7 TeV
(Springer-Verlag, 2013-05)
A measurement is presented of the t[bar over t] production cross section (σ[subscript t[bar over t]]) in proton-proton collisions at a centre-of-mass energy of 7 TeV, in the all-jet final state that contains at least ...
Inclusive Search for Supersymmetry Using Razor Variables in pp Collisions at √s=7 TeV
(American Physical Society, 2013-08)
An inclusive search is presented for new heavy particle pairs produced in √s=7 TeV proton-proton collisions at the LHC using 4.7±0.1 fb[superscript -1] of integrated luminosity. The selected events are analyzed in the ...
Search for supersymmetry in events with opposite-sign dileptons and missing transverse energy using an artificial neural network
(American Physical Society, 2013-04)
In this paper, a search for supersymmetry (SUSY) is presented in events with two opposite-sign isolated leptons in the final state, accompanied by hadronic jets and missing transverse energy. An artificial neural network ...
Rapidity distributions in exclusive Z + jet and γ + jet events in pp collisions at √s = 7 TeV
(American Physical Society, 2013-12)
Rapidity distributions are presented for events containing either a Z boson or a photon with a single jet in proton-proton collisions produced at the CERN LHC. The data, collected with the CMS detector at s√ = 7 TeV, ...
Measurement of the W-boson helicity in top-quark decays from t[overline t] production in lepton+jets events in pp collisions at √s =7 TeV
(Springer Berlin Heidelberg, 2013-10)
The W-boson helicity fractions in top-quark decays are measured with tt̄ events in the lepton+jets final state, using proton-proton collisions at a centre-of-mass energy of 7TeV, collected in 2011 with the CMS detector at ...
Observation of a new boson with mass near 125 GeV in pp collisions at √s =7 and 8 TeV
(Springer-Verlag/SISSA, 2013-06)
A detailed description is reported of the analysis used by the CMS Collaboration in the search for the standard model Higgs boson in pp collisions at the LHC, which led to the observation of a new boson. The data sample ...
Studies of jet quenching using isolated-photon+jet correlations in PbPb and pp collisions at √ sNN=2.76 TeV
(American Physical Society, 2013-01)
Results from the first study of isolated-photon + jet correlations in relativistic heavy ion collisions are reported. The analysis uses data from PbPb collisions at a centre-of-mass energy of 2.76 TeV per nucleon pair ...
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
(Springer-Verlag, 2013-12)
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 TeVwith the CMS detector at the LHC, for an ...
Search for a Higgs boson decaying into a Z and a photon in pp collisions at √ s = 7 and 8 TeV
(Elsevier BV, 2013)
A search for a Higgs boson decaying into a Z boson and a photon is described. The analysis is performed using proton-proton collision datasets recorded by the CMS detector at the LHC. Events were collected at center-of-mass ...
Search for supersymmetry in pp collisions at √s=7 TeV in events with a single lepton, jets, and missing transverse momentum
(Springer-Verlag, 2013-05)
Results are reported from a search for new physics processes in events containing a single isolated high-transverse-momentum lepton (electron or muon), energetic jets, and large missing transverse momentum. The analysis ...
