Many quark models, 1/Nc expansions of QCD, etc. predict spectrum of exited baryon states Predicted is a rich spectrum of exited states (the constituent quark model by S.Capstick and N.Isgur predicts 45 states below 2.3 GeV, the algebraic model by F.Iachello predicts 32 states) The constituent quark model and the algebraic model predict the most of the cascade states to be narrow Lattice QCD calculations? What is known about cascades?
