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

Abstract

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