Parameter Tuning of Three-Flavor Dynamical Anisotropic Clover Action

Presenter: Huey-Wen Lin — Jefferson Lab

Huey-Wen Lin, Robert G. Edwards, Balint Joo

We report on the determination of the anisotropy parameters of the three-flavor clover action using the Schrödinger functional. Ward identities consisting of PCAC and rotational symmetry of Wilson loops are imposed in the chiral limit, thus allowing a direct determination of the mass dependence of the anisotropy parameters. Recent calculations of the excited-state spectrum of nucleons demonstrates the efficacy of the method.
