Abstract:
We present the first results for lattice QCD at finite temperature and chemical potential with four flavors of Wilson quarks. The calculations are performed using the imaginary chemical potential method at , 0.001, 0.15, 0.165, 0.17 and 0.25, where is the hopping parameter, related to the bare quark mass and lattice spacing by . Such a method allows us to do large scale Monte Carlo simulations at imaginary chemical potential . By analytic continuation of the data with to real values of the chemical potential, we expect at each , a transition line on the plane, in a region relevant to the search for quark gluon plasma in heavy-ion collision experiments. The transition is first order at small or large quark mass, and becomes a crossover at intermediate quark mass.- 12.38.Gc
