Measurement of the top pair production cross section in the lepton+jets channel using a jet flavor discriminant
We present a new method to measure the top quark pair production cross section and the background rates with data corresponding to an integrated luminosity of 2.7fb-1 from pp̄ collisions at √s=1.96TeV collected with the CDF II Detector. We select events with a single electron or muon candidate, miss...

| description | We present a new method to measure the top quark pair production cross section and the background rates with data corresponding to an integrated luminosity of 2.7fb-1 from pp̄ collisions at √s=1.96TeV collected with the CDF II Detector. We select events with a single electron or muon candidate, missing transverse energy, and at least one b-tagged jet. We perform a simultaneous fit to a jet flavor discriminant across nine samples defined by the number of jets and b tags. An advantage of this approach is that many systematic uncertainties are measured in situ and inversely scale with integrated luminosity. We measure a top cross section of σ tt̄=7.64±0.57(stat+syst)±0.45(luminosity)pb. © 2011 American Physical Society. |
