摘要
We construct an improved soft-wall AdS/QCD model with a cubic coupling term of the dilaton and the bulk scalar field.The background fields in this model are solved by the Einstein-dilaton system with a nontrivial dilaton potential,which has been shown to reproduce the equation of state from the lattice QCD with two flavors.The chiral transition behaviors are investigated in the improved soft-wall AdS/QCD model with the solved gravitational background,and the crossover transition can be realized.Our study provides the possibility to address the deconfining and chiral phase transitions simultaneously in the bottom-up holographic framework.
