Abstract

We briefly review the formulation of chiral quark soliton model and explain the difference and similarities with the Skyrme model. Next, we apply the model to calculate non-exotic and exotic mass spectra. We concentrate on large N_c counting both for mass splittings and decay widths. It is shown that pure large N_c arguments do not explain the small width of exotic pentaquark states.
