The dependence of differential cross-section of prompt photon production in bremsstrahlung Formula: see text at collisions of nonpolarized and longitudinally polarized protons at Formula: see text GeV NICA energies on the kinematic parameters: sum of energy of the colliding protons Formula: see text, the transverse momentum Formula: see text, the cosine of the scattering angle Formula: see text(Formula: see text), the rapidity Formula: see text of photon and Formula: see text has been investigated. Differential cross-section of bremsstrahlung accounts for 0.03% of the total diferential cross section for the production of prompt photons in a proton-proton collisions at NICA entrgies. The polarization of protons has a large influence on the differential cross-section of bremsstrahlung Formula: see text, at large values of the transverse momentum of prompt photons. Double spin asymmetry of process of bremsstrahlung on the kinematic parameters has been studied.
Alizada et al. (Fri,) studied this question.
