Measurement of the inclusive isolated photon production cross section in pp collisions at √s=7 TeV

ALICE Collaboration

Research output: Contribution to journalArticle

Abstract

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<pTγ<60GeV/c. The result extends the pT coverage of previously published results of the ATLAS and CMS experiments at the same collision energy to smaller pT. 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.
