Exotic baryons and multibaryons in chiral soliton models

Abstract

Recently observed exotic baryon resonance with positive strangeness is discussed. The chiral soliton model, which allowed to predict the mass and width of this state, predicts also a number of other exotic states, strange and non-strange, some of them are, probably, observed in experiments. The existence of exotic multibaryons is expected as well, with positive strangeness or beauty, and negative charm. The possibility of binding of anticharm and antibeauty is pointed out.
