Tevatron results on b-quark cross sections and correlations

PDF Version Also Available for Download.

Description

We report on recent results obtained by the D0 and CDF collaborations on the properties of b-quark production and correlations in p{bar p} collisions at {radical}s = 1.8 TeV. The D0 experiment has measured the angular correlations between the b- and {bar b}-quarks using the azimuthal opening angle between their decay muons. This measurement is also used to extract the inclusive b-quark production cross section for |y{sub b}| < 1.0 and is combined with previous Tevatron results. The CDF experiment has made the first direct measurement of b{bar b} rapidity correlations at a hadron collider, measuring the ratio of cross ... continued below

The CDF experiment has made the first direct measurement of b{bar b} rapidity correlations at a hadron collider, measuring the ratio of cross sections obtained in two different rapidity bins. D0 has also measured the inclusive production cross section for muons originating from b-quark decays in the forward region. These results are combined with previous measurements in the central region to obtain a rapidity dependence of the b-quark production cross section.
