Finite Temperature SD Equation for Chiral Symmetry Restoration in Dual Ginzburg-Landau Theory

Abstract

We study the chiral phase transition at $T\ne 0$ in the dual Ginzburg-Landau theory using the Schwinger-Dyson (SD) equation. In order to solve the SD equation at $T\ne 0$, we provide a new ansatz for the quark self-energy in the imaginary-time formalism. The recovery of the chiral symmetry is found at $T_{{}_C}\sim 100MeV$ with realistic parameters, which are set by reproducing the values of the string tension $\sqrt{\sigma }\simeq 0.44GeV$ and the chiral condensate < {\bar q}q > \simeq -(250 MeV}^{3} at $T=0$.
