Heavy baryons in the chiral quark-soliton model: a possibility for exotica?

Abstract

We discuss possible interpretation of five excited ${\Omega }_c^0$ states within the Chrial Quark Soliton Model. We show that it is not possible to interpret all five ${\Omega }_c^0$'s as parity minus excitations and argue that two narrowest states are pentaquarks belonging to the SU(3) representation $\overline{15}$.
