WebOn the other hand, for T =0, we observe that the chiral symmetry restoration, which occurs at a finite chemical potential μ = μc, is a transition of first order. This result is also consistent with that obtained in different models of QCD [ 23, 32, 33 ]. Both the scalar susceptibility and quark susceptibility exhibit a divergence at the CEP.
