Abstract
Different formulations of the 4d compact lattice QED with staggered fe rmions (standard Wilson and modified by suppression of lattice artifac ts) are investigated by Monte Carlo simulations within the quenched ap proximation. We show that after suppressing lattice artifacts the syst em undergoes a phase transition from the Coulomb phase into a presumab ly weakly chirally broken phase only at (unphysical) negative beta-val ues.
