New Mesons in the Chirally Symmetric Plasma

Abstract

A nonperturbative proof is given that the chirally-invariant quark propagator contains both particle and hole singularities with different dispersion relations. Mesons made of a quark and a hole will produce dilepton pairs at masses characteristic of the plasma and with a distinct energy dependence.
