Beautiful exotica

The chiral quark-soliton model applied to baryons with one heavy quark predicts new exotic states belonging to three <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" display="inline"><a:mover accent="true"><a:mn mathvariant="bold">15</a:mn><a:mo stretchy="true">¯</a:mo></a:mover></a:math> 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 <f:math xmlns:f="http://www.w3.org/1998/Math/MathML" display="inline"><f:mi>b</f:mi></f:math>-baryons. We present predictions for masses of beautiful exotica and discuss the decay widths, which are either very small or relatively large.
