论文摘要
匹配和比较过去和将来的实验的测量要求需要对用于解释的计算进行一致性检查。现场理论的新方案可能优化精度，但与早期结果的比较晦涩难懂。多年来，Electroweak相互作用的改善，有效出生，有效的耦合和SIN^2theta_w^eff Complations的概念已经发展。 我们使用四个Dizet Electroweak库版本；在今天和过去30年中，WICH被用于实际上所有HEP加速器实验的现象学。版本因校正的时间更新而有所不同。我们依靠使用KKMC Monte Carlo程序存档的代码，用于E^+E^ - f bar f n（伽马）。最近可以使用模拟和存储活动的Tauspinner重新加权。 Tauspinner升级的文档，版本为2.1.0，并提供了半自动化electroweak（EW）效果的布置基准图。提供了可用于完成具有EW效果的模拟样本的详细信息。 将重点放在数值结果上，并放在改进的BORN中引入的近似值，以获得有效的出生，以与QCD校正匹配。 Tau Lepton极化P_TAU，向后的不对称A_FB和Parton级横截面Sigma^tot用于监视电动效应和有效的sin^2theta_w^eff限制。结果包括：（i）有效天生近似值和sin^2theta_w^eff的可行性，（ii）electroweak库版本之间的差异以及（iii）由于例如m_t或delta alpha_h^（5）（s）。示例结果允许评估有效天生的适当性，以提高出生。
Matching and comparing measurements of past and future experiments calls for consistency checks of calculations used for their interpretation. New schemes of the field theory may optimize precision, but obscure comparisons with earlier results. Over years concepts of Improved Born, Effective Born, effective couplings, and sin^2theta_W^eff mixing angle for electroweak interactions, have evolved. We use four DIZET electroweak library versions; of today and of the last 30 years, wich were used for phenomenology of practically all HEP accelerator experiments. Versions differ by incremented with time updates of corrections. We rely on the codes archived with the KKMC Monte Carlo program for e^+e^- to f bar f n(gamma). Versions became recently available for the TauSpinner reweighting of simulated and stored events. Documentation of TauSpinner upgrade, to version 2.1.0, and of its arrangement for semi-automated electroweak (EW) effects benchmark plots are provided. Details which can be used to complete simulated sample with EW effects, are given. Focus is placed on numerical results and on approximations introduced in Improved Born to obtain Effective Born, to match with QCD corrections. The tau lepton polarization P_tau, forward backward asymmetry A_FB and parton level cross section sigma^tot are used to monitor electroweak effects and effective sin^2theta_W^eff limitations. Results include: (i) feasibility of Effective Born approximation and sin^2theta_W^eff, (ii) differences between versions of electroweak libraries and (iii) parametric ambiguities due to e.g. m_t or Delta alpha_h^(5)(s). Example results allow to evaluate adequacy of Effective Born with respect to Improved Born.
