论文摘要
QED初始状态校正的确切知识对于研究$ E^+E^ - $ Enhihilations中LEP，国际线性撞机ILC，CLIC，giga-$ z $设施等设施中的高光度测量值至关重要。需要考虑到各种跨标准条款，最多需要$ o（α^6 l^5）$的对数校正是必要的。这既适用于$ e^+ e^ - \rightArrowγ^*/z^*$等过程的包容性测量，也适用于前进的不对称。如最近所示，可以将大量QCD的技术（例如计算大量的壳算子矩阵元素计算）用于这些计算。我们对此主题进行了介绍，并介绍了到目前为止已经达到的计算方法和数值更正。
The precise knowledge of the QED initial state corrections is of instrumental importance in studying high luminosity measurements in $e^+e^-$ annihilation at facilities like LEP, the International Linear Collider ILC, CLIC, a Giga-$Z$ facility, and the planned FCC\_ee. Logarithmic corrections of up to $O(α^6 L^5)$ are necessary with various subleading terms taken into account. This applies to both the inclusive measurement of processes like $e^+ e^- \rightarrow γ^*/Z^*$ and also the forward-backward asymmetry. As has been shown recently, techniques from massive QCD, such as the computation of massive on-shell operator matrix elements, can be used for these calculations. We give an introduction to this topic and present both the calculation methods and the numerical corrections having been reached so far.
