Inclusive b-hadron production cross section with muons in pp collisions at vs = 7 TeV

Abstract: A measurement of the b-hadron production cross section in proton-proton collisions at ?s = 7 TeV is presented. The dataset, corresponding to 85 nb?1, was recorded with the CMS experiment at the LHC using a low-threshold single-muon trigger. Events are selected by the presence of a muon with transverse momentum p µT > 6 GeV with respect to the beam direction and pseudorapidity |?µ| < 2.1. The transverse momentum of the muon with respect to the closest jet discriminates events containing b hadrons from background. The inclusive b-hadron production cross section is presented as a function of muon transverse momentum and pseudorapidity. The measured total cross section in the kinematic acceptance is ?(pp ? b + X ? µ + X0 ) = 1.32 ± 0.01(stat) ± 0.30(syst) ±0.15(lumi)µb.
