Soliton Picture for Pentaquarks

Abstract

In this talk I report on a thorough comparison between the bound state and rigid rotator approaches to generate baryon states with non--zero strangeness in chiral soliton models. This comparison shows that the scattering amplitude in the bound state approach contains contributions generated by the exchange of the rigid pentaquark excitation, and that the two approaches are consistent with each other in the large $N_C$ limit. The comparison paves the way to unambiguously compute the width of the ${\Theta }^{+}$ pentaquark in chiral soliton models.
