Abstract

We summarize the results obtained in the UA1 experiment on the production of bottom quarks in proton-antiproton collisions at √ s=0.63 TeV. Independent muon data samples are used to determine the bottom quark production cross section in different transverse momentum ranges from 6 to 30 GeV. A recent theoretical calculation to O(α s 3) of the inclusive bottom quark transverse momentum spectrum in hadronic collisions shows reasonable agreement with the data. We extrapolate the integral P T distribution to P T=0 and in rapidity to estimate the total cross section forthe production of bottom quark pairs. Assuming the shape in P T and rapidity given by the O(α s 3) calcultaion, we obtain σ( pp→b b+X) = 10.2 ±3.3 μb .
