In order to do so we formulate the quenched limit of QCD at non-zero baryon number. A first numerical analysis of this system shows that it undergoes a smooth deconfining transition. We find evidence for a region of coexisting phases that becomes broader with increasing baryon number density. Although the action is in our formulation explicitly Z(3) symmetric the Polyakov loop expectation value becomes non-zero already in the low temperature phase. It indicates that the heavy quark potential stays finite at large distances, ie. the string between static quarks breaks at non-zero baryon number density already in the hadronic phase.revised version, 25 pages, LaTeX2e file, 7 postscript filesHigh Energy Physics - LatticeHigh Energy Physics - Phenomenologytext
