Numerical Stochastic Perturbation Theory and the Gradient Flow

Abstract

We study the Yang-Mills gradient flow using numerical stochastic perturbation theory. As an application of the method we consider the recently proposed gradient flow coupling in the Schrödinger functional for the pure SU(3) gauge theory.
