摘要：

We present results of searches for the top quark in ppBAR collisions at square-root s = 1.8 TeV. The data sample was collected during 1988-1989 at the Fermilab Tevatron Collider and has an integrated luminosity of 4.1 pb-1. We have extended our previous search for e-mu final states to include the ee and mu-mu-channels. In addition, we have searched for a low-transverse-momentum muon as a tag of the bottom quark in top decay events with a lepton and at least two jets. We obtain a lower limit on the top-quark mass of 91 GeV/c2 at the 95% confidence level assuming standard-model charged-current decays.
