摘要：
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.
