Towards selecting a finite-range regularization scale
Abstract
Extensive studies have demonstrated that finite-range regularization (FRR) offers significantly improved chiral extrapolations for lattice QCD. These studies have typically relied on selecting the finite-regularization scale based upon phenomenological input. Here we report on a preliminary investigation of a procedure to determine a preferred range of FRR scale based on nonperturbative lattice results -- without any phenomenological prejudice.
