摘要：

We determine the location of the second-order end-point of the line of the first-order chiral phase transition in three-flavor QCD at vanishing baryon chemical potential (mu(B)). Using multiparameter reweighting we determine the mu(B)-dependence of the transition line. With an ansatz inspired by chiral perturbation theory, we extrapolate to the chiral critical point in (2 + 1)-flavor QCD. For both quantities we find a significant quark mass dependence.
