The DO Collaboration reports on a search for the standard model top quark in pp collisions at +s = 1.8 TeV at the Fermilab Tevatron with an integrated luminosity of approximately 50 pb '. We have searched for tt production in the dilepton and single-lepton decay channels with and without tagging of b-quark jets. We observed 17 events with an expected(More)
