摘要
In this paper we present a short overview on the dynamical holographic QCD(DhQCD)method for hadron physics and QCD matter.The five-dimensional DhQCD model is constructed in the graviton-dilaton-scalar framework with the dilaton background fieldΦand the scalar field X dual to the gluon condensate and the chiral condensate operator thus can represent the gluodynamics(linear confinement)and chiral dynamics(chiral symmetry breaking),respectively.The dilaton background field and the scalar field are a function of the 5th dimension,which plays the role of the energy scale,in this way,the DhQCD model can resemble the renormalization group from ultraviolet(UV)to infrared(IR).By solving the Einstein equation,the metric structure at IR is automatically deformed by the nonperturbative gluon condensation and chiral condensation in the vacuum.We review the results on the hadron spectra including the glueball spectra,the light/heavy meson spectra,as well as on QCD phase transitions,and thermodynamical as well as transport properties in the framework of the DhQCD model.
