Abstract
We discuss the quenched limit of lattice QCD at non-zero baryon numberdensity. We find evidence for a mixed phase that becomes broader withincreasing baryon number. Although the action is explicitly Z(3) symmetric thePolyakov loop expectation value becomes non-zero already in the low temperaturephase. It indicates that the heavy quark potential stays finite at largedistances, i.e. the string between static quarks breaks at non-zero baryonnumber density already in the hadronic phase. This behaviour is validated bycalculating the heavy quark potential using Polyakov loop correlations.
