Light quark masses from quenched lattice QCD simulations with domain wall quarks

Abstract

Values for the strange quark mass and average up/down mass have been obtained from quenched lattice QCD simulations using the domain wall fermion action. This discretization preserves the properties of flavor and chiral symmetry at nonzero lattice spacing. Results are shown for two values of the lattice spacing. The mass renormalization constant is computed nonperturbatively.Comment: To appear in the proceedings of DPF 2000, Columbus, OH, USA. Work done as part of the RIKEN/BNL/Columbia Collaboration.
