Introducing RGBeta: a Mathematica package for the evaluation of renormalization group -functions

In completely generic four-dimensional gauge-Yukawa theories, the renormalization group $$ -functions are known to the 3-2-2 loop order in gauge, Yukawa, and quartic couplings, respectively. It does, however, remain difficult to apply these results to realistic models without the use of dedicated computer tools. We describe a procedure for extracting $$ -functions using the general results and introduce RGBeta, a dedicated Mathematica package for extracting the $$ $$ -functions in broad classes of models. The package and example notebooks are available from the GitHub repository.
