Description
The production of photons with large transverse energy in hadronic
collisions is an important testing ground for perturbative Quantum
Chromodynamics (pQCD), enabling to probe parton distribution functions
(PDFs) and the parton-to-photon fragmentation functions (FFs). In
addition, high-ET photons can also constitute an irreducible background
for important searches such as H→γγ, or SUSY and extra-dimensions with
energetic photons in the final state.
We present the measurement of the cross section for the inclusive
production of isolated prompt photons in p\bar{p} collisions at the
Tevatron, using the full dataset collected with the upgraded Collider
Detector at Fermilab (CDF). Measurements are performed as a function of
the photon transverse energy in the range 30 GeV < E_T < 500 GeV and
pseudorapidity region |\eta| < 1.0. The results are compared to the
state-of-art calculations.
