Toward Bound-State Approach to Strangeness in Holographic QCD

An approach to realize a hyperon as a bound-state of a two-flavor baryon and a kaon is considered in the context of the Sakai-Sugimoto model of holographic QCD, which approach has been known in the Skyrme model as the bound-state approach to strangeness. As a simple case of study, pseudo-scalar kaon is considered as fluctuation around a baryon. In this case, strongly-bound hyperon-states are absent, different from the case of the Skyrme model. Observed is a weak bound-state which would correspond to \Lambda(1405).Comment: 13 pages, 2 figures, v2: references adde

Application of the Mutual Information to the Zn Gauge Model

We introduce the mutual information to the Zn lattice gauge theory for testing the degree of correlations. It is shown that our simulation result for the plaquettes gives a clear peak on the critical point
