"Measurement of the Inclusive Isolated Prompt Photon Cross Section at CDF"
I present results on the measurement of the inclusive direct photon production cross section in proton-antiproton collisions at #sqrt(s) = 1.96 TeV, using data collected with the upgraded Collider Detector at Fermilab in Run II, and corresponding to an integrated luminosity of 2.5 fb-1. Measurements are performed as a function of the photon transverse momentum for photons with pT > 30 GeV and |eta| < 1.0. Photons are required to be isolated in the calorimeter (isolation ET < 2 GeV). We use the calorimeter isolation distribution to estimate the contamination from jets faking isolated photons. The measured cross section is corrected back to the hadron level and compared to NLO pQCD predictions. The NLO pQCD predictions include non-perturbative corrections. We find good agreement between data and the theoretical predictions.
