Chirally symmetric but confined hadrons at finite density

Understand

At a critical finite chemical potential and low temperature QCD undergoes the chiral restoration phase transition.

• The folklore tradition is that simultaneously hadrons are deconfined and there appears the quark matter.
• We demonstrate that it is possible to have confined but chirally symmetric hadrons at a finite chemical potential and hence beyond the chiral restoration point at a finite chemical potential and low temperature there could exist a chirally symmetric matter consisting of chirally symmetric but confined hadrons.
• If it does happen in QCD, then the QCD phase diagram should be reconsidered with obvious implications for heavy ion programs and astrophysics.
