Description

The Standard Model Effective Field Theory (SMEFT) provides a powerful framework for parameterizing potential new physics in a model-independent way. In order to analyze data from experiments across different energy scales and extrapolate UV physics effects, it is crucial to know the renormalization group evolution (RGE) of SMEFT operators. In this talk, I will present the results for the two-loop running of the purely bosonic dimension six operators in the SEMFT as well as our recent progress toward the RGE of the full dimension six SMEFT at two-loop order. I will elaborate on the functional methods that we use to perform these calculations, our custom code built on top of the Mathematica package Matchete and the various challenges we encountered in this project.
