Off-forward anomalous dimensions of non-singlet transversity operators

High Energy Physics - Phenomenology 2022-05-23 v3

Abstract

We determine the anomalous dimension matrix for the transversity operator mixing into total derivative operators in the limit of a large number of quark flavors nfn_f to fourth order in the strong coupling αs\alpha_s in the MS\overline{\text{MS}}-scheme. This is achieved by using a consistency relation between the operator anomalous dimensions, which follows from the renormalization structure of the operators in the chiral limit.
