得到了极化粒子半包容深度非弹性散射最低阶辐射修正的精确解析表达式，其形式为最紧凑的协变形式，便于数值分析。利用Bardin-Shumeiko方法提取和抵消了真实光子发射的红外发散。给出了独占辐射尾的贡献。给出了在超相对论近似下的解析结果。
The explicit exact analytical expressions for the lowest-order radiative corrections to the semi-inclusive deep inelastic scattering of the polarized particles are obtained in the most compact, covariant form convenient for the numerical analysis. The infrared divergence from the real photon emission is extracted and cancelled using the Bardin-Shumeiko approach. The contribution of the exclusive radiative tail is presented.The analytic results obtained within the ultrarelativistic approximation are also show.
