摘要

The UA1 lepton samples are studied in terms of QCD heavy flavor production. Using the full O( alpha (sup 3)(sub s))QCD calculations the bottom cross section is derived: sigma(bb-bar) = 10.2 +- 3.3 mu b. Considering the large errors this is in good agreement with the theoretical value: sigma(bb-bar) = 12(sup +7)(sub -4) mu b. The isolated muon and isolated electron samples are used for the top quark search. The two samples together yield a top mass limit: m(sub t) > 44GeV/c(sup 2) at 95% C.L.. Also a limit is derived on the mass of the b', a fourth generation down-like quark: m(sub b(sup ')) > 32 GeV/c(sup 2) at 95% C.L.. The possibilities of top searches at the Spp-barS collider with ACOL and the tevatron collider are also discussed. 136 refs.; 134 figs.; 26 tabs. (Atomindex citation 20:036103)
