Pentaquark Theta(*) states in the 27-plet from chiral soliton models

摘要

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* --> KN is less than 43 MeV. We also discuss the search for the existence of Theta* states in physical processes. (C) 2004 Published by Elsevier B.V.
