The chiral limit of the two-flavor lattice Schwinger model with Wilson fermions

Abstract

We study the 2-flavor lattice Schwinger model with Wilson fermions in the chiral limit. The quark mass is determined using the PCAC definition. We numerically compute the masses of the iso-triplet (pi) and iso-singlet particles (eta) for different quark masses and compare our results with analytical formulas.
