Measurement of γ+b+X and γ+c+X production cross sections in pp̄ collisions at s=1.96TeV
2009
First measurements of the differential cross sections d 3 σ /(dp T γ dy γ dy jet ) for the inclusive production of a photon in association with a heavy quark (b, c) jet are presented, covering photon transverse momenta 30 T γ γ | jet | T jet >15 GeV. The results are based on an integrated luminosity of 1fb -1 in pp¯ collisions at √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.
