Inclusive cross sections of isolated prompt photons in pp collisions at $\sqrt{s}= 7$ TeV measured with the ATLAS detector using 4.7 $fb^{-1}$

A measurement of the cross section for the production of isolated prompt photons in pp collisions at a center-of-mass energy $\sqrt{s} = 7$ TeV is presented. The results are based on an integrated luminosity of 4.7 fb$^{-1}$ collected with the ATLAS detector at the LHC. The cross section is measured as a function of photon transverse energy $E_{T}^{\gamma}$ in the kinematic range $100 < E_{T}^{\gamma}\lt 1000$ GeV and in the pseudorapidity regions $|\eta^{\gamma}|\lt 1.37$ and $1.52\leq |\eta^{\gamma}| \lt 2.37$. The results are compared to leading-order parton-shower Monte Carlo models and next-to-leading order perturbative QCD calculations.
