Curing Fermion Mass Gauge Variance in QED2+1
Abstract
The problem of the gauge dependence of the fermion mass in the Maxwell-Chern-Simons QED2+1 is revisited. Using Proca mass term as an intermediate infrared regulator we are demonstrating gauge-invariance of the fermion mass shell in QED2+1 in all orders of the perturbation theory.
