On the scaling properties of quenched QED
Journal Article

· Physical Review. D, Particles, Fields, Gravitation and Cosmology
Critical scaling laws are studied in quenched quantum electrodynamics with induced four-fermion interactions that drive the theory to criticality. The critical exponents are calculated in the quenched, planar model and the physical picture extracted is consistent with recent results from lattice simulations. Near criticality, a composite scalar state plays an essential role in the effective dynamics.
