Study of the Associated Production of Photons and b-quark Jets in p anti-p Collisions at s**(1/2) =1.96 TeV

The cross section for photon production in association with at least one jet containing a b-quark hadron has been measured in proton antiproton collisions at s**(1/2) = 1.96 TeV. The analysis uses a data sample corresponding to an integrated luminosity of 340 pb-1 collected with the CDF II detector. Both the differential cross section as a function of photon transverse energy Egamma_T, d sigma (p anti-p --> gamma + > 1b-jet)/dEgamma_T and the total cross section sigma(p anti-p --> gamma + > 1b-jet; Egamma_T > 20 GeV) are measured. Comparisons to a next-to-leading order prediction of the process are presented.
