Description
Summary:The production cross section of inclusive isolated photons has been measured by the ALICE experiment at the CERN LHC in pp collisions at a centre-of-momentum energy of √s = 7 TeV. The measurement is performed with the electromagnetic calorimeter EMCal and the central tracking detectors, covering a range of |η| < 0.27 in pseudorapidity and a transverse momentum range of 10 < p(T)(gamma) < 60 GeV/c. The result extends the p(T) coverage of previously published results of the ATLAS and CMS experiments at the same collision energy to smaller p(T). The measurement is compared to next-to-leading order perturbative QCD calculations and to the results from the ATLAS and CMS experiments. All measurements and theory predictions are in agreement with each other.
