Cutoff effects of the gradient flow for fermions

Andrea Shindler

英文摘要:

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($a$) improvement of the action is achieved changing the initial conditions of the gradient flow equation.
