Abstract

Chiral phase transition for three-flavor $N_{f} = 2 + 1$ QCD with $m_{u} = m_{d} \neq = m_{s}$ is investigated in a modified soft-wall holographic QCD model. Solving temperature dependent chiral condensates from equations of motion of the modified soft-wall model, we extract the quark mass dependence of the order of chiral phase transition in the case of $N_{f} = 2 + 1$ , and the result is in agreement with the "Colombia Plot", which is summarized from lattice simulations and other non-perturbative methods. First order phase transition is observed around the three flavor chiral limit $m_{u / d} = 0, m_{s} = 0$ , while at sufficient large quark masses it turns to be a crossover phase transition. The first order and crossover regions are separated by a second order phase transition line. The second order line is divided into two parts by the $m_{u / d} = m_{s}$ line, and the $m_{s}$ dependence of the transition temperature in these two parts are totally contrast, which might indicate that the two parts are governed by different universality classes.
