In this paper this motivated by evidence for a chiral phase transition in strong coupling lattice QED the authors calculate the two-particle spectrum of the broken QED phase. This is done in the framework of a Nambu and Jana-Lasinio model with U(1) symmetry including chiral symmetry and symmetry breaking properties of QED. The second order chiral phase transition behavior in our model and in lattice QED are in excellent agreement. The authors then present a detailed analysis of the spectra of the e[sup +]e[sup [minus]] modes in the broken phase. The authors examine whether these modes have any possible relationship to the narrow e[sup +]e[sup [minus]] resonance found in soft heavy ion collisions at GSL. The authors' answer is negative.
