Description
Functional Methods have emerge as a crucial tool for the automation of computations in quantum field theory, particularly in the renormalization and running of theories. On top of that, these techniques can be applied to the world of EFTs through the process of matching. So far this idea has been applied up to one loop. I present a systematic procedure for going beyond, considering both fermionic and bosonic degrees of freedom. I will demonstrate how the inclusion of gauge bosons requires a new approach to the problem that was not necessary in the one-loop case. It will rely on the introduction of the Wilson line to obtain a covariant expansion.
