Measurement of the Cross Section for Direct-Photon Production in Association with a Heavy Quark inpp¯Collisions ats=1.96TeV

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 $\sqrt{s}=1.96\mathrm{TeV}$ proton-antiproton collisions corresponding to $9.1{\mathrm{fb}}^{-1}$ 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 $|y^{\gamma }|<1.0$, a heavy-quark-jet transverse momentum $p_T^{\mathrm{jet}}>20\mathrm{GeV}$, and jet rapidities $|y^{\mathrm{jet}}|<1.5$. The results are compared with several theoretical predictions.
