| Abstract: | We investigate the potential between a static quark-antiquark pair in the full QCD vacuum. The dynamical quark sea is considered both by Kogut-Susskind and Wilson fermions. Two temperatures T below and above the phase transition Tc are studied. The behavior of the interquark potential in the full quantum field is driven by the explicitly broken Z3 symmetry in the fermionic action for T<Tc and by an additional spontaneous Z3 symmetry breaking for T<Tc. |
