A pentaquark picture of Lambda(1405)
Abstract
Description
We test a pentaquark model of the negative parity hyperon Lambda(1405). We use a model where valence four quarks and one antiquark move in a potential relativistically and interact with each other and themselves through gluon and NG boson. Fall-apart decay rate of the system is studied and strong model dependence is pointed out.
