Implications of Holographic QCD in ChPT with Hidden Local Symmetry

Abstract

Based on the chiral perturbation theory (ChPT) with the hidden local symmetry, we propose a methodology to calculate 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 $\ddot{I}$-$\ddot{I}€$-$\ddot{I}€$ coupling becomes in good agreement with the experiment due to the $1/N_c$-subleading corrections.

New equations are added and several equations are displayed. New references are added. 6pages, no figures, version published to Phys.Rev.D
