Inclusive photon yields, scaled by the mean nuclear thickness function, are presented as a function of collision centrality and transverse momentum in two pseudorapidity intervals, |η|<1.37 and 1.52≤|η|<2.37. The scaled yields in the two pseudorapidity intervals, as well as the ratios of the forward yields to those at midrapidity, are compared to the expectations from next-to-leading-order perturbative QCD (pQCD) calculations. The measured cross sections agree well with the predictions for proton-proton collisions within statistical and systematic uncertainties. Both the yields and the ratios are also compared to two other pQCD calculations, one which uses the isospin content appropriate to colliding lead nuclei and another which includes nuclear modifications to the nucleon parton distribution functions.}, keywords = {heavy ion: scattering (INSPIRE) / photon: production (INSPIRE) / photon: yield (INSPIRE) / cross section: measured (INSPIRE) / lead: nucleus (INSPIRE) / nucleon: parton: distribution function (INSPIRE) / rapidity dependence (INSPIRE) / ATLAS (INSPIRE) / transverse momentum dependence (INSPIRE) / quantum chromodynamics: perturbation theory (INSPIRE) / CERN LHC Coll (INSPIRE) / statistical (INSPIRE) / isospin (INSPIRE) / experimental results (INSPIRE) / 2760 GeV-cms/nucleon (INSPIRE)}, cin = {ATLAS}, ddc = {530}, cid = {I:(DE-H253)ATLAS-20120731}, pnm = {611 - Fundamental Particles and Forces (POF3-611)}, pid = {G:(DE-HGF)POF3-611}, experiment = {EXP:(DE-H253)LHC-Exp-ATLAS-20150101}, typ = {PUB:(DE-HGF)16 / PUB:(DE-HGF)15}, eprint = {1506.08552}, howpublished = {arXiv:1506.08552}, archivePrefix = {arXiv}, SLACcitation = {$\%\%CITATION$ = $arXiv:1506.08552;\%\%$}, doi = {10.1103/PhysRevC.93.034914}, url = {https://bib-pubdb1.desy.de/record/296995}, }
