| Abstract |
We measure the &gamma + b and &gamma + c cross sections and their ratio in p-pbar collisions at sqrt{s} = 1.96 TeV. We present cross sections both as a function of photon Et in order to test QCD predictions at different energy scales, and for all photons with an Et exceeding 25 GeV to gain maximal statistical sensitivity to deviations that could signal new physics production. Results are based on 67 pb-1 of CDF Run II data. They are compared to and found to be consistent with PYTHIA Leading Order predictions.
