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 momentum pT of photons, the cosine of the scattering angle cos(θ), and the rapidity of photons y 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.
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 \({\sqrt s }\)、光子的横向动量 pT、散射角 cos(θ) 的余弦和光子的速度 y 的关系进行了研究。结果表明,纯电动子过程在 NICA 能量下产生瞬发光子的总截面中的贡献可达百分之十左右,因此在模拟和分析实验数据时应将其考虑在内。
