Off-forward anomalous dimensions of non-singlet transversity operators
arXiv:2204.02140 · doi:10.1016/j.nuclphysb.2022.115835
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 to fourth order in the strong coupling in the -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.
