Parameter dependence of the mapping of the mean-field Ising model onto QCD in the first-order phase transition regime

We map the mean-field Ising equation of state onto the QCD phase diagram and investigate how scaling parameters alter the metastable and unstable regions, as well as the symmetrized pressure and density along an isotherm on the QCD $T-μ_B$ phase plane. We find that, for both the conventional mapping
