Abstract
A nucleon saturation scheme for the algebra of Regge residues and chiral symmetry is studied. A representation of this extended algebra of SU(2) × SU(2) × O(5) includes the nucleon , the , and two other nucleon resonances. The masses for the resonances, the low-energy pionic coupling, and the Regge coupling of the , , , and trajectories to the particles present in the scheme are predicted and the results are compared with experimental numbers.
