Isolated photon production and pion-photon correlations in high-energy pp and pA collisions

Popis výsledku v původním jazyce

A phenomenological study of the isolated photon production in high energy pp and pA collisions at RHIC and LHC energies is performed. Using the color dipole approach we investigate the production cross section differential in the transverse momentum of the photon considering three different phenomenological models for the universal dipole cross section. We also present the predictions for the rapidity dependence of the ratio of pA to pp cross sections. As a further test of the formalism, for different energies and photon rapidities we analyze the correlation function in azimuthal angle Delta phi between the photon and a forward pion. The characteristic double-peak structure of the correlation function around Delta phi similar or equal to pi observed previously for Drell-Yan pair production is found for an isolated photon emitted into the forward rapidity region which can be tested by future experiments.
