Description
Renormalization Group Equations for an arbitrary gauge field theory have been known at two-loop for about 30 years. Deriving them by hand for a specific model is a very tedious task prone to errors. In order to automate this process, we released in 2014 a Python program called PyR@TE that automatically derived the RGEs for a given Lagrangian (non-SUSY).
Recently, we published the second version of this program that greatly extends the capabilities of the first version. In particular, models involving kinetic mixing are now fully supported at two-loop, and a dedicated group theory library has been developed in order to cover generic group and irreducible representations.
In this talk, an overview of PyR@TE will be given with a strong emphasis on the new capabilities.
