Prompt Photon Production in Sub-Processes $${qg \to q\gamma }$$ and $${q\gamma \to q\gamma }$$ of Compton Scattering in Proton –Proton Collision at NICA Energies

Abstract—Dependence of the differential cross section of the production of prompt photons with sub-processes of mixed chromo-electrodynamic\({qg \to q\gamma }\) and pure electrodynamic\({q\gamma \to q\gamma }\) Compton scattering on the total energy of colliding protons\({\sqrt s }\), the transverse momentumpT of photons, the cosine of the scattering angle cos( θ), and the rapidity of photonsy is studied. It has been shown that the purely electrodynamic sub-process can contribute up to the order of ten percent of the total cross-section of the production of prompt photons at NICA energies and, consequently, should be taken into account in simulating and analyzing experimental data.
