McMule --低能实验的QED修正

McMule -- QED Corrections for Low-Energy Experiments

Yannick Ulrich

摘要:

我们提出了McMule,一个统一的框架,计算的非线性光学和非线性光学修正的QED与大质量费米子的许多过程。这个易于扩展的程序允许用户计算任意可观察的任何过程实现。这些实验包括各种轻子衰变以及某些低能散射实验,如$eμ\to eμ$和$\ell p\to\ell p$,它们可以被测量到足够高的精度,以保证QED校正。作为我们讨论的一部分,我们将介绍如何进行这些计算的教学介绍,重点放在技术方面,并辅以示例。我们的目标是为那些进入该领域的人提供一个有用的介绍,涵盖与从业者相关的所有方面。

英文摘要:

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.
