Book excerpt: Recent results on top quark physics with the D0 experiment in {anti p}p collisions at √s = 1.8 TeV for an integrated luminosity of 125 pb−1 are reported. The direct measurement of the top quark mass uses single lepton events, giving the result m{sub top} = 173.3 ± 5.6(stat) ± 6.2(syst) GeV=c2. The measurement of the t{anti t} production cross section includes analyses from 8 top decay channels: dilepton (t{anti t} → e[mu], ee, and [mu][mu]), electron and neutrino (t{anti t} → e[nu]), and single leptons (t{anti t} → e + jets and t{anti t} → [mu] + jets) with and without b tagging. We measure the t{anti t} production cross section to be 5.5 ± 1.8 pb at m{sub top} = 173.3 GeV/c2.
