Mass and Isospin Breaking Effects in the Skyrme Model and in Holographic QCD
Lorenzo Bartolini, Stefano Bolognesi, Sven Bjarke Gudnason +1
We discuss how the quark masses and their mass splitting affect the baryons in the Skyrme model as well as the Witten-Sakai-Sugimoto (WSS) model. In both cases baryons are describe…

Boundary terms in the Witten-Sakai-Sugimoto model at finite density
Lorenzo Bartolini, Sven Bjarke Gudnason
We consider the Witten-Sakai-Sugimoto model in the approximation of smeared instantons at finite density via a homogeneous Ansatz, which is known to be discontinuous in order to be…
