摘要

讨论了在单规范玻色子产生的情况下，作为辐射校正的一部分的韧致辐射贡献计算问题。结果表明，硬光子韧致辐射的贡献可分为有限项和发散项。在维正则化格式的框架下，给出了软光子韧致辐射和硬光子韧致发射红外部分的精确计算。对单规范玻色子产生截面的辐射修正进行了数值分析。

Modern Technique for Real Photon Radiative Correction Calculations

The problem of the bremsstrahlung contribution calculation as a part of the radiative corrections in the case of single gauge boson production was discussed. It was shown that the hard photon bremsstrahlung contribution can be divided into the finite and divergent terms. The exact calculation of soft photon bremsstrahlung and infrared part of hard photon bremsstrahlung was presented in frame of the dimensional regularization scheme. Numerical analysis of radiative corrections to the cross sections of single gauge boson production was performed.
