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