Finite Temperature SD Equation for Chiral Symmetry Restoration in Dual Ginzburg-Landau Theory
Shoichi Sasaki, Hideo Suganuma, Hiroshi Toki
Abstract
We study the chiral phase transition at T≠ 0 in the dual Ginzburg-Landau theory using the Schwinger-Dyson (SD) equation. In order to solve the SD equation at T≠ 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 100 MeV with realistic parameters, which are set by reproducing the values of the string tension σ 0.44 GeV and the chiral condensate < qq > -(250 MeV3 at T=0.
