Measurement of gamma b X and gamma c X Production Cross Sections in pp Collisions at s=1.96 TeV (Art. No. 192002)

Abstract

First measurements of the differential cross sections d(3)sigma/(dp(T)(gamma)dy(gamma)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 { p(T)(gamma){ 150 GeV, photon rapidities |y(gamma)|{ 1.0, jet rapidities |y(jet)|{ 0.8, and jet transverse momenta p(T)(jet)} 15 GeV. The results are based on an integrated luminosity of 1 fb(-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.
