Automated EFT matching

The goal is to write a code (e.g. python, Mathematica) that takes any BSM model in a symbolic form (e.g. Feynrules) and calculates SMEFT Wilson coefficients in the low-energy effective theory up to one loop precision. The matching between BSM and SMEFT can be done using universal formulas recently obtained using functional (path integral) approach.
