Background State

We study the hydrodynamics of the nuclear matter of two flavors of light quarks with spontaneous chiral symmetry breaking based on the Poisson bracket method. The effects of mass are included and the full hydrodynamic equation for pions is given. The in-medium dispersion relation of pions in the neutron rich background state and the possibility of the phase transition to pion condensation are also discussed.

Motivated by evidence for a chiral phase transition in strong coupling lattice QED we calculate the two-particle spectrum of the broken QED phase. This is done in the framework of a Nambu and Jona-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. We then present a detailed analysis of the spectra of the e+e− modes in the broken phase. We examine whether these modes have any possible relationship to the narrow e+e− resonances found in soft heavy ion collisions at GSL. Our answer is negative.
