Abstract

The problem of the gauge dependence of the fermion mass in the Maxwell-Chern-Simons QED $_{2 + 1}$ is revisited. Using Proca mass term as an intermediate infrared regulator we are demonstrating gauge-invariance of the fermion mass shell in QED $_{2 + 1}$ in all orders of the perturbation theory.
