b-jet cross-section with vector boson production

A measurement of the cross-section for vector boson production in association with jets containing B-hadrons is presented using 35 pb-1 of data collected by the ATLAS experiment in 2010. Such processes are large, irreducible backgrounds to searches for the a low mass Higgs decaying to a pair of b-quarks produced in association with a vector boson. Theoretical predictions of the V+B production rate have large uncertainties and previous measurements have reported discrepancies. The inclusive and differential cross-sections in both the electron and muon channels will be shown. Comparisons will be made to recent theoretical predictions at the next-to-leading order.
