| We report a measurement of the production cross section for b hadrons in pp̅ collisions at √s=1.96 TeV. Using a data sample derived from an integrated luminosity of 83 pb-1 collected with the upgraded Collider Detector (CDF II) at the Fermilab Tevatron, we analyze b hadrons, Hb, partially reconstructed in the semileptonic decay mode Hb→μ-D0X. Our measurement of the inclusive production cross section for b hadrons with transverse momentum pT>9 GeV/c and rapidity |y|<0.6 is σ=1.30 μb±0.05 μb(stat)±0.14 μb(syst)±0.07 μb(B), where the uncertainties are statistical, systematic, and from branching fractions, respectively. The differential cross sections dσ/dpT are found to be in good agreement with recent measurements of the Hb cross section and well described by fixed-order next-to-leading logarithm predictions. |
