It is shown that its signal drops at a (pseudo-)critical chemical potential mu_c. The Polyakov loop and the chiral condensate undergo their transitions at the same value. Pauli blocking supervenes at a value of the chemical potential larger than mu_c.Latex file (uses espcrc2.sty), 4 pages, 4 ps figures; talk presented at QCD-06, Montpellier, July 2006High Energy Physics - LatticeHigh Energy Physics - PhenomenologyHigh Energy Physics - Theorytext
