Renormalization Group Equations of the Gauge Couplings in the Standard Model at Three-Loop Order — Luminita Mihaila, •Jens Salomon, and Matthias Steinhauser — Institut für Theoretische Teilchenphysik, Karlsruhe, Deutschland

We present the renormalization group equations of the gauge couplings in the Standard Model at three-loop order in the MS scheme. We take into account all contributions involving the Standard Model gauge couplings, the top-, bottom- and tau-Yukawa couplings and the Higgs self-coupling. We discuss our regularization prescription of the γ₅-matrix along with other details of the calculation.
