Abstract

Empirical boson assignments on the baryon-antibaryon model are used to analyze exhaustively the masses for 13 out of 16 expected P orbitals; on this basis search areas can be predicted for the missing three states, all having I=0 and JP=1+. The mass analysis alone does not necessarily require much SU3 singletoctet mixing. Extrapolation to D states appears to pose a contradiction between this model and exchange degeneracy of normal boson trajectories. The situation can be resolved empirically by determining accurate JP values for the prominent I=1 bosons in the RS region of missing-mass spectrometer assignments. Tentative evidence for a first radially excited octet with JP=0 places it in a mass region consonant with the model.
