Abstract The b-hadron production cross section is measured with the ATLAS detector in pp collisions at s = 7 TeV, using 3.3 pb1 of integrated luminosity, collected during the 2010 LHC run. The b-hadrons are selected by partially reconstructing D+μX final states. Differential cross sections are measured as functions of the transverse momentum and pseudorapidity. The measured production cross section for a b-hadron with pT > 9 GeV and |η| < 2.5 is 32.7 ± 0.8 (stat.)6.8+4.5 (syst.) μb, higher than the next-to-leading-order QCD predictions but consistent within the experimental and theoretical uncertainties.
