Abstract
We establish a holographic QCD model for four flavors, where a light scalar field and a heavy scalar field are introduced, separately. The field is responsible for the breaking of to . The ground state and its Regge excitation of meson spectra in the light flavor sector and heavy flavor sector as well as the ligh-heavy mesons are well in agreement with the Particle data group (PDG). Due to the additional introduction of the field in the model, different Regge slopes for light and heavy mesons can be achieved.
