SU( \(N_f=2+1\) ) Sakai-Sugimoto Model

We introduce a strange quark in the Sakai-Sugimoto model by collective rotation. For easier understanding, we first explain this concept in terms of Skymion, where this method has traditionally been used. We review the problem of the Chern-Simons term that arises when this method is applied to the Sakai-Sugimoto model, and how to solve it. Finally, using the dimensional reduction method proposed by Forgacs-Manton, we show one way to introduce charm and bottom quarks into the model by utilizing the extra dimensions of this model.
