Query: Heavy Flavour Production at sqrt(s)=7 TeV   The measurements of b quark, quarkonium and exotic state production performed
with the ATLAS and CMS experiments at sqrt(s)=7 TeV are presented. The b-quark
production cross section is measured both in inclusive and fully reconstructed
B hadron decays. The results are compared with QCD expectations at tree-level
and NLO.
