Abstract
We report a measurement of the production cross section for b hadrons in pp̄ collisions at s=1.96TeV. Using a data sample derived from an integrated luminosity of 83pb-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>9GeV/c and rapidity |y|<0.6 is σ=1.30μb±0.05μb(stat)±0. 14μb(syst)±0.07μb(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. © 2009 The American Physical Society.
