Abstract

We discuss several highly accurate theoretical predictions for masses of baryons containing the b quark which have been recently confirmed by experimental data. Several predictions are given for additional properties of heavy baryons. We also discuss the two charged exotic resonances Z _b with quantum numbers of a (bb-ud-) tetraquark, very recently reported by Belle in the channel [Υ{hooked} (nS)π ⁺, n=1, 2, 3]. Among possible implications are deeply bound I=0 counterparts of the Z _b-s and existence of a σb+σb- dibaryon, a beauteron.
