Isolated Pair Photon Production in the Parton Reggeization Approach

Abstract

Abstract In the article, we calculate differential cross sections for pair production of isolated photons within the parton Reggeization approach (PRA) at energies of Tevatron and LHC colliders. The calculations were performed within the KaTie parton-level event generator and improved KMRW model for unintegrated parton distribution functions. The satisfactory agreement with experimental data from ATLAS and CDF collaborations was obtained, and the estimation for photon pair production cross section at the NICA collider was performed.
