@article{Sakai2005MoreOA, title={More on a holographic dual of QCD}, author={Tadakatsu Sakai and Shigeki Sugimoto}, journal={Progress of Theoretical Physics}, year={2005}, volume={114}, pages={1083-1118} }

We investigate the interactions among the pion, vector mesons and external gauge fields in the holographic dual of massless QCD proposed in a previous paper [T. Sakai and S. Sugi-moto, Prog. Theor. Phys. 113 (2005), 843; hep-th/0412141] on the basis of probe D8-branes embedded in a D4-brane background in type IIA string theory. We obtain the coupling constants by performing both analytic and numerical calculations, and compare them with experimental data. It is found that the vector meson…
