We have measured the b-quark production cross section for |y| < 1 using a sample of dimuon events collected with the DO detector in proton antiproton collisions at √s = 1.8 Te V at the Fermilab Tevatron. The measured b-quark cross section is consistent with O(ɑ³(s)) QCD predictions, but lies at the upper limit of the theoretical uncertainties which is a factor of 1.5 above the mean value. A study of the difference in azimuthal angle of the two muons is in good qualitative agreement with the O(ɑ³(s)) QCD predictions.Type
