Query: Search for High Mass Top Quark Production in p anti-p Collisions at
  S**(1/2) = 1.8 TeV   We present new results on the search for the top quark in p anti-p collisions
at S**(1/2) = 1.8 TeV with an integrated luminosity of 13.5 +- 1.6 pb**(-1). We
have considered t anti-t production in the Standard Model using electron and
muon dilepton decay channels (t anti-t -> e mu + jets, e e + jets, and mu mu +
jets) and single-lepton decay channels (t anti-t -> e + jets and mu + jets)
with and without tagging of b quark jets. From all channels, we have 9 events
with an expected background of 3.8 +- 0.9. If we assume that the excess is due
to t anti-t production, and assuming a top mass of 180 GeV/c**2, we obtain a
cross section of 8.2 +- 5.1 pb.
