The b-hadron production cross section is measured with the ATLAS detector in pp collisions at\ud √s = 7 TeV, using 3.3 pb−1 of integrated luminosity, collected during the 2010 LHC run. The b-hadrons\ud are selected by partially reconstructing D*+μ−X final states. Differential cross sections are measured as\ud 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.)\ud +4.5\ud −6.8(syst.) μb, higher than the next-to-leadingorder\ud QCD predictions but consistent within the experimental and theoretical uncertainties.
