摘要:

利用\SANC系统计算了过程$e^+e^- \to μ^-μ^+ (τ^-τ^+)$截面的完整单圈电弱辐射修正。高阶贡献的初始状态辐射计算的QED结构函数形式主义。给出了初始粒子不同极化度下质心能量范围$\sqrt{s}=5, ~7$ ~GeV的数值结果。

英文摘要:

Complete one-loop electroweak radiative corrections to the cross section of the process $e^+e^- \to μ^-μ^+ (τ^-τ^+)$ are evaluated with the help of the \SANC system. Higher-order contributions of the initial state radiation are computed in the QED structure function formalism. Numerical results are given for the center-of-mass energy range $\sqrt{s}=5, ~7$~GeV for various polarization degrees of the initial particles.
