Search for heavy quarks decaying into a top quark and a W or Z boson using lepton plus jets events in pp collisions at root s=7 TeV
(Springer Science+Business Media, 2013-01)
Results are presented from a search for the pair-production of heavy quarks, Q (A) over bar, that decay exclusively into a top quark and a W or Z boson. The search is performed using a sample of proton-proton collisions ...
Search for invisible decays of Higgs bosons in the vector boson fusion and associated ZH production modes
(Springer Science+Business Media, 2014-08)
A search for invisible decays of Higgs bosons is performed using the vector boson fusion and associated ZH production modes. In the ZH mode, the Z boson is required to decay to a pair of charged leptons or a bb quark pair. ...
Search for physics beyond the standard model in events with tau leptons, jets, and large transverse momentum imbalance in pp collisions at root s=7 TeV
(Springer Science+Business Media, 2013-07)
A simultaneous measurement of the top-quark, W-boson, and neutrino masses is reported for t (t) over bar events selected in the dilepton final state from a data sample corresponding to an integrated luminosity of 5.0 fb(-1) ...
Search for stopped long-lived particles produced in pp collisions at root s=7 TeV
(Springer Science+Business Media, 2012-08)
A search has been performed for long-lived particles that have stopped in the CMS detector, during 7TeV proton-proton operations of the CERN LHC. The existence of such particles could be inferred from observation of their ...
Search for charge-asymmetric production of W ' bosons in t(t)over-bar + jet events from pp collisions at root s=7 TeV
(Elsevier, 2012-10-31)
A search is presented for charge-asymmetric production of a W' boson that has been proposed to accommodate the forward-backward asymmetry observed in the production of top-antitop quark pairs at the Tevatron. The new heavy ...
The performance of the CMS muon detector in proton-proton collisions at √ s = 7 TeV at the LHC
(IOP Publishing, 2013-11)
The performance of all subsystems of the CMS muon detector has been studied by using a sample of proton-proton collision data at √s = 7 TeV collected at the LHC in 2010 that corresponds to an integrated luminosity of ...
Search for excited leptons in pp collisions at root s=7 TeV
(Elsevier, 2013-03-26)
Results are presented of a search for compositeness in electrons and muons using a data sample of pp collisions at a center-of-mass energy root s = 7 TeV collected with the CMS detector at the LHC and corresponding to an ...
Observation of sequential upsilon suppression in PbPb collisions
(American Physical Society, 2012-11-30)
The suppression of the individual gamma (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 150 ...
Search for narrow resonances and quantum black holes in inclusive and b-tagged dijet mass spectra from pp collisions at root s=7 TeV
(Springer Science+Business Media, 2013-01)
A search for narrow resonances and quantum black holes is performed in inclusive and b-tagged dijet mass spectra measured with the CMS detector at the LHC. The data set corresponds to 5 fb(-1) of integrated luminosity ...
Study of exclusive two-photon production of W+W- in pp collisions at root s=7 TeV and constraints on anomalous quartic gauge couplings
(Springer Science+Business Media, 2013-07)
A search for exclusive or quasi-exclusive W+W- production by photon-photon interactions, pp -> p(*)W(+)W(-)p(*), at \/s = 7 TeV is reported using data collected by the CMS detector with an integrated luminosity of 5.05 ...
