Abstract
We have searched for evidence of top quark production in ppBAR collisi ons at square-root s = 1.8 TeV using the DO detector at the Fermilab T evatron collider. For an integrated luminosity of 15 pb-1, we report r esults of a search for ttBAR pairs in the decay modes ttBAR --> emu jets, ee + jets, e + jets, and mu + jets. From analyses of these modes we obtain a lower limit on the top quark mass of 131 GeV/c2 at the 95 % confidence level, assuming standard model branching fractions and a predicted cross section for ttBAR production. We discuss the propertie s of an event for which expected backgrounds are small.
