Simulating lattice QCD at finite density

A new method of simulating systems with a complex action which was recently introduced is applied to lattice QCD at finite density. At infinite gauge coupling we obtain a phase diagram which, in nice agreement with mean-field theory, gives a critical value of the chemical potential unrelated to the...

Zusammenfassung:A new method of simulating systems with a complex action which was recently introduced is applied to lattice QCD at finite density. At infinite gauge coupling we obtain a phase diagram which, in nice agreement with mean-field theory, gives a critical value of the chemical potential unrelated to the baryon mass. At the same time we demonstrate explicitly the failure of the quenched approximation.
