We report measurements of b-quark and B-hadron production in ppBAR collisions at square-root s = 630 GeV. We use muon data samples to extract beauty production cross-sections over a wide range of transverse momentum in the central rapidity range /y/ < 1.5. We compare our results to an O(alpha-s3) QCD prediction and find good agreement over the measured b-quark transverse momentum range 6 GeV/c to 54 GeV/c. Using the shape of the P(T) and y distributions predicted by QCD to extrapolate our data, we infer a total cross-section for b-quark production at square-root s = 630 GeV of sigma(ppBAR --> bbBAR + X) = 19.3 +/- 7 (exp.) +/- 9 (th.)mu-b.

Abstract
We report measurements of b-quark and B-hadron production in ppBAR collisions at square-root s = 630 GeV. We use muon data samples to extract beauty production cross-sections over a wide range of transverse momentum in the central rapidity range /y/ < 1.5. We compare our results to an O(alpha-s3) QCD prediction and find good agreement over the measured b-quark transverse momentum range 6 GeV/c to 54 GeV/c. Using the shape of the P(T) and y distributions predicted by QCD to extrapolate our data, we infer a total cross-section for b-quark production at square-root s = 630 GeV of sigma(ppBAR --> bbBAR + X) = 19.3 +/- 7 (exp.) +/- 9 (th.)mu-b.Pubblicazioni consigliate
