Chiral Phase Transitions

Abstract

We show that melting the quark mass, the scalar $\sigma$ mass and the quark condensate leads uniquely to the quark-level SU(2) linear $\sigma$ model field theory. Upon thermalization, the chiral phase transition curve requires $T_c=2f_{\pi }^{CL}\approx 180MeV$ when $\mu =0$, while the critical chemical potential is ${\mu }_c=m_q\approx 325MeV$. Transition to the superconductive phase occurs at $T_c^{(SC)}=\Delta /\pi e^{-{\gamma }_E}$. Coloured diquarks suggest $T_c^{(SC)}<180MeV$.
