Possibility of the existence of charmed exotica

We employ the chiral quark-soliton model to describe excited baryons with one heavy quark. Identifying known charmed baryons with multiplets allowed by the model, we argue that apart from regular excitations of the ground-state multiplets, two out of five narrow Ωc0 states, recently reported by the LHCb Collaboration, may correspond to the exotic pentaquarks. This interpretation can be easily verified experimentally, since exotic Ωc0 states-contrary to the regular excitations-form isospin triplets rather than singlets.
