Abstract

We suggest that the correlated narrow-peak structures observed in heavy-ion collisions are due to decays of $e^{+}$ $e^{-}$ and γγ systems formed in a new confining phase of QED.

A similar model has been proposed in Ref. 7. However the authors of Ref. 7 used the nonrelativistic Schrödinger equation. The main advantage of our approach is that one can discuss both the $e^{+}$ $e^{-}$ and γ gamma spectra.
These approximations should introduce a theoretical uncertainty of order of 10 keV.
