Abstract

The cut-off effects of the lattice gradient flow - often called Wilson flow - are calculated on a periodic 4-torus at leading order in the gauge coupling. A large class of discretizations is considered which includes all frequently used cases in practice. It is shown how the results lead to a smoother continuum extrapolation for the ß-function of SU(3) gauge theory with Nf = 4 flavors of fermions.
