Abstract: (APS)

The possibility that the ΔD35(1925) resonance is evidence for a [56, 1−] multiplet corresponding to excitation of new gluonic degrees of freedom within baryons is examined in detail. A new group-theoretical analysis of a successful mass formula for the N=2 multiplets of the nonrelativistic harmonic-oscillator quark model is also presented. Some results for the N=3 level are also given together with an outline of the method for generalization to any degree of excitation of the system.
