Abstract

The bosonization technique has been recently applied by Hirata and Minakata to the study of supercritical QED around a large-Z nucleus. New charge-neutral metastable states emerge from the spectrum of the theory and their existence represents a possible explanation of the e+e− peaks observed in heavy-ion collisions. Actually, we suspect that such metastable states are a mere product of the approximations introduced in the treatment of the bosonized Hamiltonian. In order to support our conjecture about the origin of the new states we show that they are not suppressed by an external field approximation where both the fermion-fermion interaction and the quantum fluctuations of the electromagnetic field are removed from the bosonized formulation of QED.
