Four loop renormalization of three-quark operators in QCD

Year: 2026

Type: article

Abstract: We renormalize generalized three-quark operators that relate to baryon states using the method devised by Kränkl and Manashov at four loops in the MS ¯ scheme. The anomalous dimensions of the four core operators used to compute nucleon matrix elements are determined and their associated critical exponents are studied in the conformal window using the Banks-Zaks expansion.
