PyR@TE 3

We present a new version of PyR@TE, Python tool for the computation renormalization group equations general, non-supersymmetric gauge theories. Its core relies on recent paper by Poole & Thomsen (arXiv:1906.04625) to compute $\beta$-functions. In this framework, kinetic mixing is naturally implemented, and Weyl consistency relations between gauge, quartic Yukawa couplings are automatically satisfied. One main features possibility user coupling $\beta$-functions up three-loop order. Large parts PyR@TE code have been rewritten improved, including theory module PyLie. As result, overall performance in terms speed was drastically improved model file more flexible user-friendly.
