McMule -- QED Corrections for Low-Energy Experiments

Understand

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 $e\mu\to e\mu$ 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.
