OSTI ID:381731
We report a number of results on beauty production from the D{null} experiment at the Fermilab Tevatron Collider operating at {radical}s = 1.8 TeV. Measurements of the {ital b}{ital {anti b}} production cross section using single muon, muon plus jet and dimuon plus jet triggers, in the data collected in 1992-93, are presented. A preliminary measurement of the {ital b}{ital {anti b}} angular correlations using the dimuon data sample is also presented. We find that the {ital b}-quark production cross section for {vert_bar}{ital Y}{sup b}{vert_bar} {lt} 1.0 and {ital p}{sub T}{sup b} {gt} 8 GeV/c is systematically higher than, although consistent within errors with, the next-to-leading order (NLO) QCD predictions. A similar comparison with QCD is observed in the {ital b}{ital {anti b}} ({mu}{mu}) angular correlations, where the shape of the distribution indicates a sizable contribution fro the NLO process.
