We report on a preliminary measurement of the inclusive dimuon cross section in p{bar p} collisions at (square root)s = 1.8 TeV using the D0 detector at the Fermilab Tevatron. From these results, we extract the inclusive b-quark production cross section for the kinematic range {vert_bar}y{sup b}{vert_bar}

We report on the measurement of inclusive muon and b quark production by the D0 collaboration in p[bar p] collisions at[radical]s= 1.8 TeV at the Fermilab Tevatron Collider. The results represent a refined analysis of the previously published 1992--93 data. We measure the muon cross section due to b quark decays over the kinematic range 4p[sub T][sup[mu]]

We report on the measurement of inclusive muon and b quark production by the D0 collaboration in p{bar p} collisions at √s = 1.8 TeV at the Fermilab Tevatron Collider. The results represent a refined analysis of the previously published 1992--93 data. We measure the muon cross section due to b quark decays over the kinematic range 4 p{sub T}{sup?}

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.

We report on a measurement of the ratio of b-quark production cross section in p{ovr p} collisions at (square root)s = 630 GeV and (square root)s = 1800 GeV collected by the Collider Detector at Fermilab. Results are compared to the predictions of next-to-leading order QCD calculations. 16 refs., 4 figs.

Inclusive J/? and?(2S) production has been studied in p{bar p} collisions at √s = 1.8 TeV with the Collider Detector at Fermilab. The products of production cross section times the branching fraction of J/?(?(2S)) to??− are reported as functions of the J/?(?(2S)) P{sub T} in the kinematic range P{sub T}> 6 GeV/c and {vert_bar}?{vert_bar} ≤ 0.5. The products of the integrated cross section times branching fraction and the b-quark production cross section calculated from these values are also reported.
