Exotic baryon resonances and the model of chiral solitons


Institute for Nuclear Research, Russian Academy of Sciences, prosp. 60-letiya Oktyabrya 7a, Moscow, 117312, Russian Federation

A recently observed baryonic resonance with positive strangeness is discussed. The state is exotic because valence quarks alone cannot produce it and at least one quark-antiquark pair must be involved. The mass of the resonance is in agreement with chiral soliton models, which predict a number of other exotic states with different quantum numbers. Some of these states (e.g., those with strangeness S =-2 and charges Q = 0,-2) are probably already being observed experimentally.
