Abstract

We investigate the rapidity and transverse-momentum distributions of the prompt photon production at the CERN LHC energies considering the current perturbative QCD approaches for this scattering process. Namely, we compare the predictions from the usual NLO pQCD calculations to the color-dipole formalism, using distinct dipole cross sections. Special attention is paid to parton-saturation models at high energies, which are expected to be important at the forward rapidities in pp collisions ( \(\sqrt{s}=14\)  TeV) at the LHC.
