We report a measurement of the production cross section for b hadrons in pp collisions at {radical}(s)=1.96 TeV. Using a data sample derived from an integrated luminosity of 83 pb{sup -1} collected with the upgraded Collider Detector (CDF II) at the Fermilab Tevatron, we analyze b hadrons, H{sub b}, partially reconstructed in the semileptonic decay mode H{sub b}{yields}{mu}{sup -}D{sup 0}X. Our measurement of the inclusive production cross section for b hadrons with transverse momentum p{sub T}>9 GeV/c and rapidity |y|<0.6 is {sigma}=1.30 {mu}b{+-}0.05 {mu}b(stat){+-}0.14 {mu}b(syst){+-}0.07 {mu}b(B), where the uncertainties are statistical, systematic, and from branching fractions, respectively. The differential cross sections d{sigma}/dp{sub T} are found to be in good agreement with recent measurements of the H{sub b} cross section and well described by fixed-order next-to-leading logarithm predictions.
