The UA1 lepton samples are studied in terms of QCD heavy flavour production. Using the full O(\(\alpha _s^3\) ) QCD calculations the bottom cross-section is derived: σ(bb̄) = 10.2 ± 3.3 µb. Considering the large errors this is in good agreement with the theoretical value: \(\sigma (b\bar b) = 12_{ - 4}^{ + 7}\mu b\) .

The isolated muon and isolated electron samples are used for the top quark search. The two samples together yield a top mass limit: mt>44 GeV/c2 at 95 % C.L.. Also a limit is derived on the mass of the b′, a fourth generation down-like quark: mb’>32 GeV/c2 at 95 % C.L..

The possibilities of top searches at the SppS collider with ACOL and at the Tevatron collider are also discussed.
