Abstract

We present a measurement of the top quark pair (tt̄) production cross section (σtt̄) in pp̄ collisions at a center-of-mass energy of 1.96 TeV using 230 pb-1 of data collected by the DØ detector at the Fermilab Tevatron Collider. We select events with one charged lepton (electron or muon), large missing transverse energy, and at least four jets, and extract the tt̄ content of the sample based on the kinematic characteristics of the events. For a top quark mass of 175 GeV, we measure σtt̄=6.7-1.3+1.4(stat) -1.1+1.6(syst)±0.4(lumi) pb, in good agreement with the standard model prediction. © 2005 Elsevier B.V. All rights reserved.
