Off-forward anomalous dimensions in the leading-$n_f$ limit

High Energy Physics - Phenomenology 2022-06-10 v1

Abstract

We review the computation of off-forward anomalous dimensions in the limit of a large number of quark flavors nfn_f. The method is based on a consistency relation the anomalous dimensions have to obey, which is a direct consequence of the renormalization structure of the operators in the chiral limit. In addition, we present a way to generate the anomalous dimensions to all orders in the strong coupling αs\alpha_s. This is based on exact conformal symmetry at the Wilson-Fisher critical point and provides an extension of previous calculations of this type for the forward anomalous dimensions.
