Abstract

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