The differential cross section is presented as a function of the photon transverse energy in different regions of photon pseudorapidity. The differential cross section as a function of the absolute value of the photon pseudorapidity is also presented in different regions of photon transverse energy. Next-to-leading-order QCD calculations from Jetphox and Sherpa as well as next-to-next-to-leading-order QCD calculations from Nnlojet are compared with the measurement, using several parameterisations of the proton parton distribution functions. The predictions provide a good description of the data within the experimental and theoretical uncertainties.eninfo:eu-repo/semantics/openAccessHadron-Hadron scattering (experiments)Photon productionQCDArticle2-s2.0-8507427019810.1007/JHEP10(2019)203Q1WOS:000495862600001
