全息QCD奇异性的边界态方法

Toward Bound-State Approach to Strangeness in Holographic QCD

Takaaki Ishii

摘要:

本文在Sakai-Sugimoto全息QCD模型的背景下考虑了一种实现超子为双味重子和K介子的束缚态的方法,这种方法在Skyrme模型中被称为奇异性的束缚态方法。作为一个简单的例子,赝标K介子被认为是围绕重子的涨落。在这种情况下,不存在强束缚超子态,这与Skyrme模型的情况不同。观察到的是一个弱束缚态,对应于Λ(1405)。

英文摘要:

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 Λ(1405).
