Description

Measurements of the inclusive photon production performed by the ATLAS collaboration are reported in different fiducial regions covering a wide acceptance. Comparisons to the data of next-to-leading order QCD calculations MCFM and JetPhox with different PDFs are presented. The theoretical uncertainties, including scale, strong coupling, and PDF uncertainties are evaluated. The cross sections for photons produced in association with jets are also measured by the ATLAS collaboration as functions of photon and jet kinematics and are compared to next-to-leading-order QCD calculations.
