McMule is a framework for fully differential higher-order QED calculations of scattering and decay processes involving leptons. It keeps finite lepton masses, which regularises collinear singularities. Soft singularities are treated with dimensional regularisation and using FKS$^\ell$ subtraction. We describe the implementation of the framework in Fortran 95, list the processes that are currently implemented, and give instructions on how to run the code. In addition, we present new phenomenological results for muon-electron scattering and lepton-proton scattering, including the dominant NNLO corrections. While the applications presented focus on MUonE, MUSE, and P2, the code can be used for a large number of planned and running experiments.

与McMule在NNLO进行QED

McMule是用于对涉及轻子的散射和衰减过程进行全差分高阶QED计算的框架。它保持着有限的轻子质量，从而使共线奇点正规化。软奇异点通过维数正则化并使用FKS $ ^ \ ell $减法来处理。我们描述了Fortran 95中该框架的实现，列出了当前实现的过程，并提供了有关如何运行代码的说明。此外，我们提出了用于μ子电子散射和轻子-质子散射的新现象学结果，包括主要的NNLO校正。虽然展示的应用程序集中在MUonE，MUSE和P2上，但是该代码可用于大量计划中和正在运行的实验。
