QCD at non-zero baryon density is expected to have a critical point where the zero-density crossover turns into a first order phase transition. To identify this point we scan the density-temperature space using a canonical ensemble method. For a given temperature, we plot the chemical potential as a function of density looking for an “S-shape” as a signal for a first order transition. We carried out simulations using Wilson fermions with mπ ≈ 1GeV on 63 × 4 lattices. As a benchmark, we ran four flavors simulations where we observe a clear signal. In the two flavors case we do not see any signal for temperatures as low as 0.83Tc. Preliminary results for the three flavor case are also presented.
