Search for supersymmetry in pp collisions at √s=7 TeV in events with a single lepton, jets, and missing transverse momentum
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 ...
Measurement of masses in the t[bar over t] system by kinematic endpoints in pp collisions at s√=7 TeV
A simultaneous measurement of the top-quark, W-boson, and neutrino masses is reported for tt events selected in the dilepton final state from a data sample corresponding to an integrated luminosity of 5.0 fb[superscript ...
Measurement of the t[bar over t] production cross section in the τ+jets channel in pp collisions at √s =7 TeV
The top-quark pair production cross section in 7 TeV center-of-mass energy proton–proton collisions is measured using data collected by the CMS detector at the LHC. The measurement uses events with one jet identified as ...
Observation of a new boson with mass near 125 GeV in pp collisions at √s =7 and 8 TeV
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 ...
Identification of b-quark jets with the CMS experiment
(IOP Publishing, 2013-04)
At the Large Hadron Collider, the identification of jets originating from b quarks is important for searches for new physics and for measurements of standard model processes. A variety of algorithms has been developed by ...
Energy calibration and resolution of the CMS electromagnetic calorimeter in pp collisions at √s = 7 TeV
(IOP Publishing, 2013-09)
The energy calibration and resolution of the electromagnetic calorimeter (ECAL) of the CMS detector have been determined using proton-proton collision data from LHC operation in 2010 and 2011 at a centre-of-mass energy of ...
Search for the standard model Higgs boson produced in association with a top-quark pair in pp collisions at the LHC
Measurement of the sum of WW and WZ production with W+dijet events in pp collisions at √s = 7 TeV
A measurement of the inclusive WW+WZ diboson production cross section in proton–proton collisions is reported, based on events containing a leptonically decaying W boson and exactly two jets. The data sample, collected at ...
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
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 ...
Measurement of the B[0 over s] → μ[superscript +]μ[superscript -] Branching Fraction and Search for B[superscript 0] → μ[superscript +]μ[superscript -] with the CMS Experiment
(American Physical Society, 2013-09)
Results are presented from a search for the rare decays B[0 over s] → μ[superscript +]μ[superscript -] and B[superscript 0] → μ[superscript +]μ[superscript -] in pp collisions at √s = 7 and 8 TeV, with data samples ...
