AI中文摘要：
在本文中，我们计算了NICA能量下质子-质子碰撞中瞬发光子产生的康普顿散射子过程$qg \rightarrow q\gamma$微分截面的次领头阶，分别考虑了碰撞质子无纵向极化和有纵向极化的情况。结果表明，次领头阶对微分截面的贡献在碰撞质子高能时显著，约占领头阶计算的$15\\%$。碰撞质子极化对次领头阶计算的影响比领头阶计算更为显著。
英文摘要：
In the presented article, the next-to-the-leading-order calculation of the differential cross-section of the Compton scattering subprocess $qg \rightarrow qγ$ for prompt photon production in proton-proton collisions at NICA energies has been carried out, both without and taking into account the longitudinal polarization of colliding protons. It is shown that the contribution of the next-to-leading order to the differential cross-section is significant at high energies of colliding protons and constitutes around $15\%$ of the leading-order calculation. The influence of the polarization of colliding protons on the next-to-leading-order calculation is more significant than on the leading-order calculation.
