    Abstract:
    The ATLAS experiment has measured the production cross section of events with two isolated photons in the final state, in proton-proton collisions at √s=7TeV. The full data set acquired in 2010 is used, corresponding to an integrated luminosity of 37pb -1. The background, consisting of hadronic jets and isolated electrons, is estimated with fully data-driven techniques and subtracted. The differential cross sections, as functions of the di-photon mass (m γγ), total transverse momentum (p T,γγ), and azimuthal separation (Δφ γγ), are presented and compared to the predictions of next-to-leading-order QCD. © 2012 CERN.
