Resumo: A measurement of the differential cross-section for the inclusive production of isolated prompt photons in pp collisions at a center-of-mass energy View the MathML sources=7 TeV is presented. The measurement covers the pseudorapidity ranges |η|<1.37|η|<1.37 and 1.52⩽|η|<2.371.52⩽|η|<2.37 in the transverse energy range 45⩽ET<400 GeV45⩽ET<400 GeV. The results are based on an integrated luminosity of 35 pb−135 pb−1, collected with the ATLAS detector at the LHC. The yields of the signal photons are measured using a data-driven technique, based on the observed distribution of the hadronic energy in a narrow cone around the photon candidate and the photon selection criteria. The results are compared with next-to-leading order perturbative QCD calculations and found to be in good agreement over four orders of magnitude in cross-section.
