Measurement of the production cross sections for a Z boson and one or more b jets in pp collisions at sqrt(s) = 7 TeV

Abstract (data abstract)
CERN-LHC. The production of a Z boson, decaying into two leptons and produced in association with one or more b-jets, is studied using proton-proton collisions delivered by the LHC at a centre-of-mass energy of 7 TeV. The data were recorded in 2011 with the CMS detector and correspond to an integrated luminosity of 5 inverse femtobarns. The Z(ll) + b-jets cross sections (where ll = mu mu or ee) are measured separately for a Z boson produced with exactly one b-jet, with at least two b-jets and at least one b-jet. In addition, a cross section ratio is extracted for a Z boson produced with at least one b-jet, relative to a Z boson produced with at least one jet.
