摘要We give a further study on chiral phase diagram in the improved soft-wall AdS/QCD model with 2 + 1 flavors. The equations of motion for the octet pscudoscalar, vector, and axial-vector mesons arc derived to compute the octet meson spectra and relevant decay constants, by which the model parameters are determined. The chemical potential effects on thermal transition of chiral condensate are investigated, which enables us to obtain the chiral phase diagram in the mu - T plane. We find that the critical endpoint linking the crossover transition with the first-order phase transition still exists and locates at (mu(B), T-c) similar or equal to (390 MeV, 145 MeV), which along with the crossover line are consistent with lattice result and experimental analysis from relativistic heavy ion collisions.
