摘要：
We present a detailed analysis, in the framework of the MFA approach, of the critical behaviour of the lattice Schwinger model with Wilson fermions on lattices up to 24(2), through the study of the Lee-Yang zeros and the specific heat. We find compelling evidence for a critical line ending at kappa = 0.25 at large beta. Finite size scaling analysis on lattices 8(2), 12(2), 16(2), 20(2) and 24(2) indicates a continuous transition. The hyperscaling relation is verified in the explored beta region.
