Description

Exploiting the relation between real-space Wilsonian renormalization group transformations and gradient flow, we show how to determine the $\beta$ function and obtain the QCD $\Lambda$ parameter. Moreover, we use this framework to develop a novel nonperturbative renormalization scheme for local operators. We demonstrate our method using nonperturbative results based on simulations with $N_f=2$ stout-smeared Möbius domain-wall fermions and Symanzik gauge action.
