Phase diagram of QCD at finite temperature and chemical potential from lattice simulations with dynamical Wilson quarks
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.Comment: Published versio
