From the Sakai-Sugimoto model to the generalized Skyrme model
From the Sakai-Sugimoto model to the generalized Skyrme model
We derive the generalized Skyrme model as a low-energy effective model of the Sakai-Sugimoto model. The novelty with the past is the presence of the sextic term equal to the topological charge squared. This term appears when the $\ensuremath{\omega}$ meson, and the tower of states on top of it, are …
