Pentaquark $\Theta^*$ States in {27} Baryon Multiplet from Chiral Soliton Model

Abstract

We estimate the mass and the width of pentaquark $\Theta^*$ states in the 27-plet from chiral soliton models. The calculations show that the mass of $\Theta^*$ is about 1.60 GeV and the width for the process $\Theta^*\to {KN}$ is less than 43 MeV. We also discuss the search for the existence of $\Theta^*$ states in physical processes.
