Three-loop beta functions in the Standard Model and beyond — •Florian Herren1, Luminita Mihaila2, and Matthias Steinhauser11Institut für Theoretische Teilchenphysik, Karlsruhe Institute of Technology (KIT) — 2Institut für Theoretische Physik, Universität Heidelberg

We review the beta functions of the Standard Model (SM) couplings to three-loop order. In particular, we provide a first independent calculation of the Yukawa coupling beta functions and discuss our calculational setup and the treatment of γ5.

Furthermore, we turn to extensions of the SM and present the gauge and Yukawa coupling beta functions for the general two-Higgs-doublet model.
