Abstract

A measurement of the b-hadron production cross section in proton-proton collisions at sqrt(s) = 7TeV is presented. The dataset, corresponding to 85 nb1, 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 pT > 6 GeV with respect to the beam direction and pseudorapidity jj < 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 ! + X0) = 1:32 0:01(stat) 0:30(syst) 0:15(lumi)b.
