We measure the tt-bar production cross section in pp-bar 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 σ(tt)-bar=7.62±0.85 pb, assuming the current world average m(t)=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.
