Abstract
We present a measurement of the top quark pair (tt̅) production cross section (σtt̅) in pp̅ collisions at √s=1.96 TeV using 230 pb-1 of data collected by the DØ experiment at the Fermilab Tevatron Collider. We select events with one charged lepton (electron or muon), missing transverse energy, and jets in the final state. We employ lifetime-based b-jet identification techniques to further enhance the tt̅ purity of the selected sample. For a top quark mass of 175 GeV, we measure σtt̅=8.6+1.6-1.5(stat.+syst.) ± 0.6(lumi.) pb, in agreement with the standard model expectation.
