A proof of concept for matchete: an automated tool for matching effective theories Fuentes Martín, Javier König, Matthias Pagès, Julie Thomsen, Anders Eller Wilsch, Felix Studying the impact of new-physics models on low-energy observables necessitates matching to effective field theories at the relevant mass thresholds. We introduce the first public version of Matchete, a computer tool for matching weakly-coupled models at one-loop order. It uses functional methods to directly compute all matching contributions in a manifestly gauge-covariant manner, while simplification methods eliminate redundant operators from the output. We sketch the workings of the program and provide examples of how to match simple Standard Model extensions 2023-09-06T09:35:44Z 2023-09-06T09:35:44Z 2023-07-25 journal article Fuentes-Martín, J., König, M., Pagès, J. et al.
