Abstract

The dual quark condensate Σ(n) proposed recently as a new order parameter of the spontaneous breaking of the Z3 symmetry are evaluated by the Polyakov-loop extended Nambu-Jona-Lasinio (PNJL) model, where n are winding numbers. The Polyakov-loop extended Nambu-Jona-Lasinio model well reproduces lattice QCD data on Σ(1) measured very lately. The dual quark condensate Σ(n) at higher temperatures is sensitive to the strength of the vector-type four-quark interaction in the Polyakov-loop extended Nambu-Jona-Lasinio model and hence a good quantity to determine the strength.
