论文摘要
本文介绍了$ e^+e^ - \至l^-l^+$散射的高精度理论预测。使用{\ tt sanc}系统执行计算。他们考虑到完整的一环辐射辐射校正以及初始梁的纵向极化。使用螺旋度振幅法获得了反应可观察物，并考虑到初始状态和最终状态质量。给出了质量中心能量范围$ \ sqrt {s} = 250-1000 $ GEV的数值结果，具有不同程度的极化。
This paper presents the high-precision theoretical predictions for $e^+e^- \to l^-l^+$ scattering. Calculations are performed using the {\tt SANC} system. They take into account complete one-loop electroweak radiative corrections as well as longitudinal polarization of initial beams. Reaction observables are obtained using the helicity amplitude method with taking into account initial and final state fermion masses. Numerical results are given for the center-of-mass energy range $\sqrt{s}=250-1000$ GeV with various degrees of polarization.
