Two-loop Renormalization Group Equations in the Standard Model

arXiv:hep-ph/0207271 · doi:10.1103/PhysRevLett.90.011601

Abstract

Two-loop renormalization group equations in the standard model are re-calculated. A new coefficient is found in the beta-function of the quartic coupling and a class of gauge invariants are found to be absent in the beta-functions of hadronic Yukawa couplings. The two-loop beta-function of the Higgs mass parameter is presented in complete form.
