We report a measurement of the production cross section for b hadrons in pp-bar collisions at √s=1.96 TeV. Using a data sample derived from an integrated luminosity of 83 pb[superscript -1] collected with the upgraded Collider Detector (CDF II) at the Fermilab Tevatron, we analyze b hadrons, H[subscript b], partially reconstructed in the semileptonic decay mode H[subscript b]→μ-D[superscript 0] X. 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/dp[subscript T] are found to be in good agreement with recent measurements of the H[subscript b] cross section and well described by fixed-order next-to-leading logarithm predictions.
