# Low energy hadron physics in holographic QCD

@article{Sakai2005LowEH, title={Low energy hadron physics in holographic QCD}, author={Tadakatsu Sakai and Shigeki Sugimoto}, journal={Progress of Theoretical Physics}, year={2005}, volume={113}, pages={843-882} }

We present a holographic dual of four-dimensional, large N_c QCD with massless flavors. This model is constructed by placing N_f probe D8-branes into a D4 background, where supersymmetry is completely broken. The chiral symmetry breaking in QCD is manifested as a smooth interpolation of D8 - anti-D8 pairs in the supergravity background. The meson spectrum is examined by analyzing a five-dimensional Yang-Mills theory that originates from the non-Abelian DBI action of the probe D8-brane. It is…
