First measurements of the differential cross sections d{sup 3}{sigma}/(dp{sub T}{sup {gamma}}dy{sup {gamma}}dy{sup jet}) for the inclusive production of a photon in association with a heavy quark (b, c) jet are presented, covering photon transverse momenta 30<p{sub T}{sup {gamma}}<150 GeV, photon rapidities |y{sup {gamma}}|<1.0, jet rapidities |y{sup jet}|<0.8, and jet transverse momenta p{sub T}{sup jet}>15 GeV. The results are based on an integrated luminosity of 1 fb{sup -1} in pp collisions at {radical}(s)=1.96 TeV recorded with the D0 detector at the Fermilab Tevatron Collider. The results are compared with next-to-leading order perturbative QCD predictions.
