Study of the underlying event at forward rapidity in pp collisions at root s=0.9, 2.76, and 7 TeV
(Springer Science+Business Media, 2013-04)
The underlying event activity in proton-proton collisions at forward pseudorapidity (-6.6 < eta < -5.2) is studied with the CMS detector at the LHC, using a novel observable: the ratio of the forward energy density, ...
Study of the dijet mass spectrum in pp -> W + jets events at root s=7 TeV
(American Physical Society, 2012-12-21)
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 ...
Study of Z production in PbPb and pp collisions at (Formula presented.) TeV in the dimuon and dielectron decay channels
(Springer International Publishing, 2015-03)
The production of Z bosons is studied in the dimuon and dielectron decay channels in PbPb and pp collisions at sNN−−−−√=2.76sNN=2.76 TeV, using data collected by the CMS experiment at the LHC. The PbPb data sample ...
Search for supersymmetry in final states with a single lepton, b-quark jets, and missing transverse energy in proton-proton collisions at root s=7 TeV
(American Physical Society, 2013-03-05)
A search motivated by supersymmetric models with light top squarks is presented using proton-proton collision data recorded with the CMS detector at a center-of-mass energy of root s = 7 TeV during 2011, corresponding to ...
Search for flavor changing neutral currents in top quark decays in pp collisions at 7 TeV
(Elsevier, 2013-01-29)
The results of a search for flavor changing neutral currents in top quark decays t -> Zq in events with a topology compatible with the decay chain t (t) over bar -> Wb + Zq -> lvb + llq are presented. The search is performed ...
Searches for supersymmetry using the MT2 variable in hadronic events produced in pp collisions at 8 TeV
(Springer Science+Business Media, 2015-05)
Searches for supersymmetry (SUSY) are performed using a sample of hadronic events produced in 8 TeV pp collisions at the CERN LHC. The searches are based on the M T2 variable, which is a measure of the transverse momentum ...
Search for supersymmetry in final states with missing transverse energy and 0, 1, 2, or >= 3 b-quark jets in 7 TeV pp collisions using the variable alpha(T)
(Springer Science+Business Media, 2013-01)
A search for supersymmetry in final states with jets and missing transverse energy is performed in pp collisions at a centre-of-mass energy of root s = 7 TeV. The data sample corresponds to an integrated luminosity of 4.98 ...
Search for new physics in events with same-sign dileptons and jets in pp collisions at s√s = 8 TeV
(Springer Nature, 2014-01)
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 ...
Erratum to: Measurement of jet multiplicity distributions in tt¯ production in pp collisions at s√=7TeV
(Springer International Publishing, 2015-05)
Search for new physics in events with same-sign dileptons and b-tagged jets in pp collisions at root s=7 TeV
(Springer Science+Business Media, 2012-08)
A search for new physics is performed using isolated same-sign dileptons with at least two b-quark jets in the final state. Results are based on a 4.98 fb(-1) sample of proton-proton collisions at a centre-of-mass energy ...
