THE CONTINUUM-LIMIT OF NON COMPACT QED

Since four-fermion operators in strongly coupled QED are nonperturbati vely renormalizable, we analyze here the phase diagram and critical be haviour of the Gauged Nambu-Jona Lasinio model. Our mean field approxi mation relates the critical exponents along the continuous phase trans ition line with the mass dependence of the chiral condensate in the Co ulomb phase of standard noncompact QED. The numerical results for nonc ompact QED strongly suggest non mean field exponents along the critica l line.
