Available in PDF, EPUB and Kindle. Book excerpt: We present a preliminary measurement of the b-quark production cross section in p{anti p} collisions at (square root)s = 630 GeV. The analysis is based on 340 nb−1 of data collected with the D0 detector at the Fermilab Tevatron Collider. We determine the ratio of the b-quark production cross sections at 630 GeV to 1800 GeV and compare our results with the CDF and UA1 measurements, and with the next-to- leading order QCD predictions.
