摘要：

We show the existence of a pseudogap phase in the Nambu-Jona-Lasinio model of quark interactions. In the pseudogap phase chiral symmetry is restored but q (q) over bar pseudoscalar mesons still exist and they are massive. Such a behavior is intermediate between a BCS superconductor and a Bose-Einstein Condensate. We suggest the relevance of this phenomenon for an understanding of recent lattice QCD and experimental data.
