Beautiful Exotica

Abstract

The Chiral Quark--Soliton Model applied to baryons with one heavy quark predicts new exotic states belonging to three $\overline{15}$ SU(3) multiplets. Here, we extend previous analysis of charm exotica to the case of beauty. All model parameters are fixed from the charm sector and from the nonexotic $b$--baryons. We present predictions for masses of beautiful exotica and discuss the decay widths, which are either very small or relatively large.
