Renormalization Group Flow in non-compact QED with two charged staggered Fermions
Abstract
We have investigated a system with two sets of staggered fermions with charges 1 and -1/2 coupling to a non-compact U(1) gauge field in 4 dimensions. The model exhibits breaking of chiral symmetries of both fermions at different values of beta. Chiral condensates, renormalized fermion masses and renormalized charges have been measured. The renormalized charges show agreement with one-loop perturbation theory. We examine surfaces of constant renormalized charges in the space of bare parameters.
