论文摘要
我们提出了McMule，这是将NLO和NNLO校正计算为QED中的许多过程的统一框架。该易于扩展的程序允许用户为实施的任何过程计算可观察到的任意观察。其中包括各种Lepton腐烂以及某些低能散射实验，例如$eμ\至Eμ$和$ \ ell p \ to \ ell p $，可以测量到足够高的精度以进行保证QED校正。 作为讨论的一部分，我们将介绍如何执行这些计算的教学介绍，重点关注补充示例的技术方面。我们的目标是为进入该领域的人提供有用的介绍，涵盖与从业者相关的所有方面。
We present McMule, a unified framework for the calculation of NLO and NNLO corrections to many processes in QED with massive fermions. This easily extendable program allows users to calculate an arbitrary observable for any of the processes implemented. These include various lepton decays as well as certain low-energy scattering experiments such as $eμ\to eμ$ and $\ell p\to\ell p$ that can be measured to high enough a precision to warrant QED corrections. As part of our discussion, we will present a pedagogical introduction to how these calculations are performed, focusing on technical aspects supplemented with examples. Our goal is to provide a useful introduction for those entering the field, covering all aspects relevant for the practitioner.
