Description
Due to large scale separations, matching is an essential and laborious computational step in the comparison of high-energy new physics models to experimental data.
Matchete is a Mathematica package that automates the one-loop matching from any generic ultraviolet (UV) model to a low-energy effective field theory (EFT) including, but not limited to, SMEFT. The program takes a UV Lagrangian as input, integrates out heavy degrees of freedom using functional methods, and returns the EFT Lagrangian. The output is further reduced to a minimal basis using Fierz identities, integration by parts, simplification of Dirac and group structures, and field redefinitions.
After reviewing the theory of functional matching, I will demonstrate the capabilities of the package with a concrete example.
