Implications of holographic QCD in chiral perturbation theory with hidden local symmetry

Based on the chiral perturbation theory with the hidden local symmetry, we propose a methodology to calculate a part of the large N-c corrections in the holographic QCD (HQCD). As an example, we apply the method to an HQCD model recently proposed by Sakai and Sugimoto. We show that the rho-pi-pi coupling is in good agreement with the experiment due to the 1/N-c-subleading corrections.
