Performance of τ-lepton reconstruction and identification in CMS
(IOP Publishing, 2012-01-01)
The performance of τ-lepton reconstruction and identification algorithms is studied using a data sample of proton-proton collisions at s = 7 TeV, corresponding to an integrated luminosity of 36 pb-1 collected with the CMS ...
Observation of long-range, near-side angular correlations in pPb collisions at the LHC
(Elsevier, 2012-11)
Results on two-particle angular correlations for charged particles emitted in pPb collisions at a nucleon–nucleon center-of-mass energy of 5.02 TeV are presented. The analysis uses two million collisions collected with the ...
Measurement of the inclusive production cross sections for forward jets and for dijet events with one forward and one central jet in pp collisions at √s = 7 TeV
(Springer-Verlag, 2012-06)
The inclusive production cross sections for forward jets, as well for jets in dijet events with at least one jet emitted at central and the other at forward pseudorapidities, are measured in the range of transverse momenta ...
Search for pair produced fourth-generation up-type quarks in pp collisions at √s = 7 TeV with a lepton in the final state
(Elsevier, 2012-10)
The results of a search for the pair production of a fourth-generation up-type quark (t′) in proton–proton collisions at √s = 7 TeV are presented, using data corresponding to an integrated luminosity of about 5.0 ...
Search for the Standard Model Higgs Boson Decaying to W[superscript +]W[superscript -] in the Fully Leptonic Final State in pp Collisions at √s = 7 TeV
(Elsevier, 2012-03)
A search for the standard model Higgs boson decaying to W[superscript +]W[superscript −] in pp collisions at √s = 7 TeV is reported. The data are collected at the LHC with the CMS detector, and correspond to an integrated ...
Measurement of the single-top-quark t-channel cross section in pp collisions at √s = 7 TeV
(Springer Nature, 2012-12)
A measurement of the single-top-quark t-channel production cross section in pp collisions at √s=7 TeV with the CMS detector at the LHC is presented. Two different and complementary approaches have been followed. The first ...
Study of the Dijet Mass Spectrum in pp→W+jets Events at √s=7 TeV
(American Physical Society, 2012-12)
We report an investigation of the invariant mass spectrum of the two jets with highest transverse momentum in pp→W+2-jet and W+3-jet events to look for resonant enhancement. The data sample corresponds to an integrated ...
Observation of Sequential Υ Suppression in PbPb Collisions
(American Physical Society, 2012-11)
The suppression of the individual Υ(nS) states in PbPb collisions with respect to their yields in pp data has been measured. The PbPb and pp data sets used in the analysis correspond to integrated luminosities of ...
Inclusive and differential measurements of the t[bar over t] charge asymmetry in proton-proton collisions at √s = 7 TeV
(Elsevier, 2012-09)
The t[bar over t] 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 ...
Search for physics beyond the standard model in events with a Z boson, jets, and missing transverse energy in pp collisions at √s =7 TeV
(Elsevier B.V., 2012-09)
A search is presented for physics beyond the standard model (BSM) in events with a Z boson, jets, and missing transverse energy (Emiss[over]T) This signature is motivated by BSM physics scenarios, including supersymmetry. ...
