Description
Recent discoveries of the Ξb, Σb, and Σb* baryons at the Tevatron are in good agreement with model-independent mass predictions made a decade ago based on a combined expansion in 1/Nc, 1/mQ, and SU(3) flavor symmetry breaking. Using the new experimental data as input, mass predictions for the undiscovered bottom baryons Ξb', Ξb*, Ωb, and Ωb* and for many unmeasured bottom baryon mass splittings are updated. The observed ground state charm baryons exhibit the mass hierarchy previously predicted by the 1/Nc, 1/mQ, and SU(3) flavor-breaking expansion
