摘要：We discuss how the choice of lattice geometry affects methods to extract the lowest-order lowenergy constants S and F of chiral pertubation theory that are based on the equivalence of random matrix theory (RMT) and QCD in the epsilon regime. We show how to minimize systematic deviations from RMT by an optimal choice of lattice geometry in the case of two light quark flavors. Finally, we determine the low-energy constants S and F from configurations of JLQCD with two dynamical overlap fermions.
