Abstract
We give a further study on chiral phase diagram in the improved soft-wall AdS/QCD model with flavors. The equations of motion for the octet pseudoscalar, vector and axial-vector mesons are 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 plane. We find that the critical end point linking the crossover transition with the first-order phase transition still exists and locates at , which along with the crossover line are consistent with lattice result and experimental analysis from relativistic heavy ion collisions.
