Three-loop Yukawa matrix beta functions in the Standard Model and beyond — •Florian Herren1, Luminita Mihaila2, and Matthias Steinhauser1 — 1Institut für Theoretische Teilchenphysik, Karlsruhe Institute of Technology (KIT) — 2Institut für Theoretische Physik, Universität Heidelberg
We present the calculation of Yukawa matrix beta functions to three loops in the two-Higgs-doublet model and the SM. Special emphasis is put on the problems arising in the computation of beta functions if the Lagrangian under consideration contains unphysical parameters, as is the case for the SM and 2HDMs. Furthermore, we present practical solutions to the aforementioned problems.
