$\text{RGE++}:$ A $\text{C++}$ library to solve renormalisation group equations in quantum field theory

Abstract

In recent years three-, four- and five-loop beta functions have been computed for various phenomenologically interesting models. However, most of these results have not been implemented in easy to use software packages. $\text{RGE++}$ bridges this gap by providing a flexible, template-based, $\text{C++}$ library to solve renormalisation group equations. Furthermore, we implement the available beta functions for the Standard Model, the minimal supersymmetric extension of the Standard Model and two-Higgs-doublet models, as well as right-handed neutrino extensions of the former two.
