# DsixTools: The Standard Model Effective Field Theory Toolkit

## TL;DR

DsixTools is a comprehensive Mathematica package designed for analyzing the Standard Model Effective Field Theory, enabling full one-loop Renormalization Group Evolution and operator matching across different energy scales.

## Contribution

It introduces a new software toolkit that automates complex calculations in SMEFT, including RGE running and operator matching, previously done manually or with limited tools.

## Key findings

- Automates one-loop RGE evolution of Wilson coefficients.
- Provides operator matching between SMEFT and Weak Effective Theory.
- Facilitates analysis of new physics effects in flavor observables.

## Abstract

We present DsixTools, a Mathematica package for the handling of the dimension-six Standard Model Effective Field Theory. Among other features, DsixTools allows the user to perform the full one-loop Renormalization Group Evolution of the Wilson coefficients in the Warsaw basis. This is achieved thanks to the SMEFTrunner module, which implements the full one-loop anomalous dimension matrix previously derived in the literature. In addition, DsixTools also contains modules devoted to the matching to the $\Delta B = \Delta S = 1,2$ and $\Delta B = \Delta C = 1$ operators of the Weak Effective Theory at the electroweak scale and their QCD and QED Renormalization Group Evolution below the electroweak scale.
