Abstract
An model of baryons, which had earlier been used by Mitra and Ross for the evaluation of the strong decay widths of negative parity (70,) baryons, is now extended to higher-lying baryonic states assumed to belong to the (56,) and (70,) representations, as Regge recurrences of the supermultiplets (56,) and (70,), respectively. Four different classes of supermultiplet transitions are examined. For the transitions (56,) → (56,), the results are in broad agreement with experiment, as well as those of and previous quark-model calculations. For the transitions (56,) → (56,) and (56,) → (70,), appreciable widths are predicted for several experimentally observable states, the first type being geometrically related to the coupling constant, and the second type being shown to involve a symmetry transition of only one unit (from symmetric to mixed symmetric wave functions). Results are also given for transitions from (70,) states.
