| Abstract |
The single inclusive bottom jet cross section is measured for events containing a Z boson in p-pbar collisions at sqrt{s} = 1.96 TeV using the Collider Detector at Fermilab. Z bosons are identified in their electron and muon decay modes. b-jets with Et > 20 GeV and | eta | < 1.5 are identified by reconstructing a secondary decay vertex. The measurement is based on an integratd luminosity of 337 pb-1 for the electron decay mode and 324 pb-1 for the muon decay mode. We find a cross section of Sigma (Z+bjet, Z->l+l-) = 0.96 ± 0.35 pb and the fraction of b-jets to the total number of jets in this sample is 2.39 ± 0.86 %. This measurement is in agreement with NLO QCD predictions.
