[en] The Anti-de Sitter/Conformal Field Theory (AdS/CFT) correspondence between theories in AdS space and conformal field theories in physical space-time provides as analytic, the semi-classical model for strongly-coupled QCD. In this work, we investigate properties of the octet baryon in the holographic model, calculate the coupling constant between π meson-octet baryon in the framework holographic model by considering the infrared-modified 5D conformal mass and Yukawa coupling of the bulk baryon field. Predictions of this model for the mass spectrum of the baryon octet are appropriate with the experimental value. It means the hard-wall AdS/QCD model is favorable for determining coupling constants between elementary particles
