Original language description
Submitted on 14 Jan 2009 (v1), last revised 4 Sep 2009 (this version, v2)) Abstract: We present a measurement of the top quark pair production cross section in ppbar collisions at /sqrt{s}=1.96 TeV using approximately 1 fb^{-1} of data collected with theD0 detector. We consider decay channels containing two high pt charged leptons where one lepton is identified as an electron or a muon while the other lepton can be an electron, a muon or a hadronically decaying tau lepton. For a mass of the top quark of 170 GeV, the measured cross section is 7.5 +1.0-1.0 (stat) +0.7-0.6 (syst) +0.6-0.5 (lumi) pb. Using lepton+tau events only, we measure: /sigma_ttbar /times B(ttbar to ltau bbbar) = 0.13 +0.09-0.08 (stat) +0.06-0.06 (syst) +0.02-0.02 (lumi) pb.
