N2 - We discuss several highly accurate theoretical predictions for masses of baryons containing the b quark which have been recently confirmed by experimental data. Proper treatment of the color-magnetic hyperfine interaction in QCD is crucial for obtaining these results. Several predictions are given for additional properties of heavy baryons. We also discuss the two charged exotic resonances Zb with quantum numbers of a (bbud) tetraquark, very recently reported by Belle in the channel [γ (nS)π+, n = 1, 2, 3]. Among possible implications are deeply bound I= 0 counterparts of the Zb-s and existence of a Σb+Σ b- dibaryon, a beauteron.
