Perspective on properties of renormalization schemes at high loops

Year: 2024

Type: conference-paper

Abstract: We report on recent work on a class of renormalization schemes in QCD, termed the MOMt schemes. None of the renormalization group functions of the eight QCD MOMt schemes involve even zetas to five loops. A new scheme is introduced for scalar $\phi^3$ theory in six dimensions where the full Laurent series in the regularizing parameter of the Green's function is absorbed into the renormalization constants. Designated as the MaxSbar scheme it is equivalent to the MOMt scheme in the critical dimension.
