The b-hadron production cross section is measured with the ATLAS detector in pp collisions at √s = 7 TeV, using 3.3 pb[superscript −1] of integrated luminosity, collected during the 2010 LHC run. The b-hadrons are selected by partially reconstructing D*[superscript +]μ[superscript −]X 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 p[subscript T] > 9 GeV and |η| < 2.5 is 32.7 ± 0.8(stat.)[+4.5 over −6.8](syst.) μb, higher than the next-to-leading-order QCD predictions but consistent within the experimental and theoretical uncertainties.
