On the width of collective excitations in chiral soliton models

Abstract

In chiral soliton models for baryons the computation of hadronic decay widths of baryon resonances is a long standing problem. For the three flavor Skyrme model I present a solution to this problem that satisfies large--$N_C$ consistency conditions. As an application I focus on the hadronic decay of the $\Theta$ and $\Theta^*$ pentaquarks.
