Abstract
A measurement of the inclusive bottom jet cross section is presented for events containing a boson in collisions at using the Collider Detector at Fermilab. bosons are identified in their electron and muon decay modes, and jets with and are identified by reconstructing a secondary decay vertex. The measurement is based on an integrated luminosity of about . A cross section times branching ratio of is found, where is the branching ratio of the boson or into a single flavor dilepton pair ( or ) in the mass range between 66 and . The ratio of jets to the total number of jets of any flavor in the sample, within the same kinematic range as the jets, is . Here, the uncertainties are the quadratic sum of statistical and systematic uncertainties. Predictions made with next-to-leading order QCD agree, within experimental and theoretical uncertainties, with these measurements.
