Cutoff effects of the gradient flow for fermions

High Energy Physics - Lattice 2023-01-23 v1

Abstract

I analyze cutoff effects of the gradient flow for Wilson-type fermions. I show that with a proper choice of the higher dimensional fields in the Symanzik effective theory, O(aa) improvement of the action is achieved changing the initial conditions of the gradient flow equation.
