Quark masses from quenched overlap fermions

Abstract

We compute light and strange quark masses for quenched overlap fermions at two values of the gauge coupling. The renormalisation is done non-perturbatively. We test the predictions of quenched chiral perturbation theory for the quark mass dependence of the hadron spectrum and see evidence for the existence of chiral logs.
