Abstract:
We study the chiral critical behaviors of QED by using Non-Perturbative Renormalization Group (NPRG). Taking account of the non-ladder contributions, our flow equations are free from the gauge parameter () dependence. We clarify the chiral phase structure, and calculate the anomalous dimension of , which is enhanced compared to the ladder approximation. We find that the cutoff scheme dependence of the physical results is very small.- quantum electrodynamics
