Measurement of the cross section for direct-photon production in association with a heavy quark in pp¯ collisions at vs=1.96 TeV

Abstract: We report on a measurement of the cross section for direct-photon production in association with a heavy quark using the full data set of ?s=1.96??TeV proton-antiproton collisions corresponding to 9.1??fb?1 of integrated luminosity collected by the CDF II detector at the Fermilab Tevatron. The measurements are performed as a function of the photon transverse momentum, covering a photon transverse momentum between 30 and 300 GeV, photon rapidities |y?|<1.0, a heavy-quark-jet transverse momentum pjetT>20??GeV, and jet rapidities |yjet|<1.5. The results are compared with several theoretical predictions.
