SuperTracer: a calculator of functional supertraces for one-loop EFT matching

We present SuperTracer, a Mathematica package aimed at facilitating the functional matching procedure for generic UV models. This package automates the most tedious parts of one-loop functional matching computations. Namely, the determination and evaluation of all relevant supertraces, including loop integration and Dirac algebra manipulations. The current version of SuperTracer also contains a limited set of output simplifications. However, a further reduction of the output to a minimal basis using Fierz identities, integration by parts, simplification of Dirac structures, and/or light field redefinitions might still be necessary. The code and example notebooks are publicly available at1

Automated summary

SuperTracer is a Mathematica package designed to simplify the functional matching computations for generic UV models, automating tedious tasks. Users may still need to further reduce the output using various methods.
