Renormalization of non-local gluon operators in lattice perturbation theory

Abstract

In this study, we investigate the renormalization of a complete set of gauge-invariant non-local gluon operators up to one-loop in lattice perturbation theory. Our computations have been performed in both dimensional and lattice regularizations, using the Wilson gluon action, leading to the renormalization functions in the modified Minimal Subtraction $(\overline{\text{MS}})$ scheme, as well as conversion factors from the modified regularization invariant $(R{I}^{\prime })$ scheme to $\overline{\text{MS}}$.
