We investigate in detail the chiral thermal transition of QCD an improved soft-wall AdS/QCD model with a simply modified 5D conformal mass bulk scalar field. also present calculation this for light meson spectra and other low-energy characteristic quantities including pion form factor, π–ρ coupling constant decay constants π, ρ, a1, which are shown to result good agreement experimental data except constant. The behavior condensate is studied. It found that such incorporates crossover indicated by lattice simulations. expected temperature can be obtained.
