Vellidis, and Tingjun Yang Abstract We report a measurement of the cross section for direct photon production in associated with a heavy quark (b or c) jet in ppbar collisions at sqrt{s} = 1.96 TeV. The data sample used corresponds to an integrated luminosity of 9.1 fb-1 collected with the CDF II detector. Measurements are performed as a function of the photon transverse energy, covering photon transverse energy 30 < ET< 300 GeV, photon rapidities |y|<1.0, jet transverse energy ETjet > 20 GeV, and jet rapidities |yjet|<1.5.
