Leading QCD-induced four-loop contributions to the β-function of the Higgs self-coupling in the SM and vacuum stability
We present analytical results for the leading top-Yukawa and QCD contribution to the β-function for the Higgs self-coupling λ of the Standard Model at four-loop level, namely the part ∝ y 4 g 6 independently confirming a result given in [1]. We also give the contribution ∝ y 2 g …
