Abstract:

Low-energy experiments allow for some of the most precise measurements in particle physics, such as g-2. To make the most of these experiments, theory needs to match the experimental precision. Over the last decade, this meant that even in QED next-to-next-to-leading order calculations (or even more in some cases) became necessary.

I will discuss some of the challenges faced when dealing with QED corrections and discuss some possible solutions that we have implemented in McMule (Monte Carlo for MUons and other LEptons). McMule is a framework that we have developed to obtain NNLO predictions for a number of processes, such as $e\mu \to e\mu$, $ee \to ee$ and $\mu \to e\nu\bar\nu$.
