论文摘要
McMule是用于散射和衰减过程的完全差异高阶QED计算的框架。它可以使有限的轻子群众群体，这通常是共线奇点。软奇异性通过维度正则化处理，并使用FKS $^\ ell $减法处理。我们描述了Fortran 95中框架的实现，列出了当前实施的过程，并提供有关如何运行代码的说明。此外，我们为哑光 - 电子散射和Lepton-Proton散射（包括主要的NNLO校正）提出了新的现象学结果。虽然申请专注于Muone，Muse和P2，但该代码可用于大量计划和运行的实验。
McMule is a framework for fully differential higher-order QED calculations of scattering and decay processes involving leptons. It keeps finite lepton masses, which regularises collinear singularities. Soft singularities are treated with dimensional regularisation and using FKS$^\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.
