abstract
Multi-spin valued states of the Rarita-Schwinger type (k/2, k/2) ⊕ [(1/2, 0) ⊕ (0, 1/2)] with k = 1, 3, and 5 are found to be realized in the excitation spectra of the light-quark baryons. We conjecture that the above multi-resonance clusters may take their origin from a QCD string described by means of a linear action.
