Abstract
We measure the tt̅ production cross section in pp̅ collisions at √s=1.96 TeV in the lepton+jets channel. Two complementary methods discriminate between signal and background: b tagging and a kinematic likelihood discriminant. Based on 0.9 fb-1 of data collected by the D0 detector at the Fermilab Tevatron Collider, we measure σtt̅ =7.62±0.85 pb, assuming the current world average mt=172.6 GeV. We compare our cross section measurement with theory predictions to determine a value for the top-quark mass of 170±7 GeV.
