Measurement of gamma + c + X and gamma + b + X production cross sections at sqrt(s) = 1.96 TeV

The photon plus heavy-flavour quark (b, c) final state provides a unique and valuable window into both the sea quark content of the proton and the splitting of gluons into heavy-flavour quark pairs. A new combination of experimental techniques has provided the basis for the first measurements of the differential gamma + c + X and gamma + b + X production cross sections at sqrt(s) = 1.96 TeV. The measurements use ~1 fb-1 of data from p-pbar collisions collected with the D0 detector.

Measurements of Photon Plus Heavy Flavor Jet Cross Sections

Measurements of differential photon + c jet and photon + b jet production cross sections are presented using approximately 1 fb-1 of data collected by the D0 detector at the Tevatron proton-antiproton collider at a center-of-mass energy of 1.96 TeV. Isolated photons are selected in the rapidity range |y| < 1.0 and jets selected with rapidities |y| < 0.8. The measurements are compared to next-to-leading order theoretical predictions.
