| Abstract |
We present preliminary results on the measurement of the inclusive direct photon production cross section
in proton-antiproton collisions at
√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 |η| <
1.0. Photons are required to be isolated in the calorimeter. 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.
