abstract

  • We demonstrate that the hypothesis of asymptotic level realization of SU(3) in the algebra [Ai,Aj]=ifijkVk added to the assumption that a ninth I=0, JP=12+ baryon Λ′ exists with a mass around 1700 MeV implies that deviations from the good results of SU(6) or SU(6) O(3) schemes can be derived theoretically, without invoking the notion of SU(6) symmetry. The Cabibbo angles are determined to be sinθV=0.227±0.008 and sinθA=0.224±0.037. We find that D(D+F)0.678. Hyperon semileptonic decays in the presence of the Λ′ are analyzed in detail. Partial widths for several 32+→12++π decays and branching ratios for the strong decay modes of the Λ′ are discussed. © 1976 The American Physical Society.
