SU(3) classification of baryon states — •Maxim Polyakov — Institut für Theoretische Physik II, Ruhr-Universität Bochum

We review the spectrum of all baryons with the mass less than approximately 2000-2200 MeV using methods based on the approximate flavor SU(3) symmetry of the strong interaction. The application of the Gell-Mann--Okubo mass formulae and SU(3)-symmetric predictions for two-body hadronic decays allows us to successfully catalogue almost all known baryons in twenty-one SU(3) multiplets. This classification allows us to make predictions for new baryonic states and excludes some of claimed in the literature baryons.
