摘要：

We present a search for electroweak production of single top quarks in the electron + jets and muon + jets decay channels. The measurements use approximate to 90 pb(-1) of data from Run 1 of the Fermilab Tevatron collider, collected at 1.8 TeV with the D empty set detector between 1992 and 1995. We use events that include a tagging muon, implying the presence of a b jet. to set an upper limit at the 95% confidence level on the cross section for the s-channel process p (p) over bar --> tb + X of 39 ph. The upper limit for the t-channel process p (p) over bar --> tqb + X is 58 pb.
