## 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 T and chemical potential {mu} with four flavors of Wilson quarks. The calculations are performed using the imaginary chemical potential method at {kappa}=0,0.001,0.15,0.165,0.17 and 0.25, where {kappa} is the hopping parameter, related to the bare quark mass m and lattice spacing a by {kappa}=1/(2ma+8). Such a method allows us to do large scale Monte Carlo simulations at imaginary chemical potential {mu}=i{mu}{sub I}. By analytic continuation of the data with {mu}{sub I}<{pi}T/3 to real values of the chemical potential, we expect at each {kappa} set-membership sign [0,{kappa}{sub chiral}], a phasemore »
