Measurement of the b-jet production cross section for events containing a Z boson produced in pˉp collisions at √s=1.96 TeV, using data corresponding to an integrated luminosity of 2 fb−1 collected by the CDF II detector at the Tevatron. Z bosons are selected in the electron and muon decay modes. Jets are considered with transverse energy ET>20 GeV and pseudorapidity |η|<1.5. The ratio of the integrated Z + b-jet cross section to the inclusive Z production cross section is measured differentially in jet ET, jet η, Z-boson transverse momentum, number of jets, and number of b-jets. The first two measurements have an entry for each b-jet in the event, the last three measurements have one entry per event.
