We present new results on the search for the top quark in pp̄ collisions at s = 1.8 TeV with an integrated luminosity of 13.5+/-1.6 pb-1. We have considered tt̄ production in the standard model using electron and muon dilepton decay channels ( tt̄-->eμ + jets, ee + jets, and μμ + jets) and single-lepton decay channels ( tt̄-->e + jets and μ + jets) with and without tagging of b quark jets. From all channels we have nine events with an expected background of 3.8+/-0.9. If we assume that the excess is due to tt̄ production, and assume a top mass of 180 GeV/ c2, we obtain a cross section of 8.2+/-5.1 pb.
