A magnetically charged disorder parameter is used to detect the deconfining transition in two color QCD at finite temperature and density. We note that a finite density of baryonic matter induces the disappearing of dual superconductivity and that this phenomenon coincides with the restoration of chiral symmetry also at finite density, at last in the range of temperatures explored. The onset of the unphysical saturation transition is studied as well, and a warning is given about the possible effects that the Pauli blocking could have at strong coupling.

Abstract

A magnetically charged disorder parameter is used to detect the deconfining transition in two color QCD at finite temperature and density. We note that a finite density of baryonic matter induces the disappearing of dual superconductivity and that this phenomenon coincides with the restoration of chiral symmetry also at finite density, at last in the range of temperatures explored. The onset of the unphysical saturation transition is studied as well, and a warning is given about the possible effects that the Pauli blocking could have at strong coupling.
