Abstract
A measurement of the cross section for the production of isolated prompt photons in collisions at a center-of-mass energy is presented. The results are based on an integrated luminosity of collected with the ATLAS detector at the LHC. The cross section is measured as a function of photon pseudorapidity and transverse energy in the kinematic range and in the regions and . The results are compared to leading-order parton-shower Monte Carlo models and next-to-leading-order perturbative QCD calculations. Next-to-leading-order perturbative QCD calculations agree well with the measured cross sections as a function of and .
