# A holographic QCD and excited baryons from string theory

@article{Park2008AHQ, title={A holographic QCD and excited baryons from string theory}, author={Jaemo Park and Piljin Yi}, journal={Journal of High Energy Physics}, year={2008}, volume={2008}, pages={011-011} }

We study baryons of arbitrary isospin in a stringy holographic QCD model. In this D4-D8 holographic setting, the flavor symmetry is promoted to a gauge symmetry in the bulk, and produces, as KK modes of the gauge field, pions and spin one mesons of low energy QCD. Baryons of arbitrary isospins are represented as instanton solitons with isospin and spin quantum numbers locked, in a manner similar to the Skyrmion model. The soliton picture leads to a natural effective field theory of arbitrary…
