Critical behavior in quenched QED to all orders in the coupling
Description
We determine the cutoff dependence of the gauge coupling α to all orders in perturbation theory for a quenched QED scenario by stability analysis of the CJT effective potential. We then derive the expression for the beta function of the system in the supercritical phase. The model seems to possess a nontrivial continuum limit in the language of renormalization group flow. We also determine the dynamical mass function in the supercritical phase to all orders in α. (orig.)
