Measurement of the tt̅ production cross section in pp collisions at 7 TeV in lepton+jets events using b-quark jet identification
A new measurement of the inclusive production cross section for pp→[¯ over tt] is performed at a center-of-mass energy of 7 TeV using data collected by the CMS experiment at the LHC. The analysis uses a data sample corresponding to an integrated luminosity of 36 pb[superscript -1], and is based on...

| description | A new measurement of the inclusive production cross section for pp→[¯ over tt] is performed at a center-of-mass energy of 7 TeV using data collected by the CMS experiment at the LHC. The analysis uses a data sample corresponding to an integrated luminosity of 36 pb[superscript -1], and is based on the final state with one isolated, high transverse momentum muon or electron, missing transverse energy, and hadronic jets. The tt[over ¯] content of the selected events is enhanced by requiring the presence of at least one jet consistent with b-quark hadronization. The measured cross section is 150±9(stat)±17(syst)±6(lumi) pb and is in agreement with higher-order QCD calculations. The combination of this measurement with a previous CMS result based on dileptons gives 154±17(stat+syst)±6(lumi) pb. |
