D0 findings on the top quark

Recent results on top quark physics with the D0 experiment in pp collisions at {radical}s = 1.8 TeV are reported. The direct measurement of the top quark mass uses single lepton and dilepton events, giving the result m{sub top} = 172.1 {+-} 7.1 GeV/c{sup 2} . The measurement of the t{anti t} production cross section includes analyses from 9 top decay channels: dilepton, electron and neutrino, single leptons with and without b tagging, and all-jets (t{anti t} {r_arrow} b jets). The authors measured the t{anti t} production cross section to be 5.9 {+-} 1.7 pb at m{sub top} = 172.1 GeV/c{sup 2}. Preliminary results on a search for charged Higgs production in top events are presented
