Description

Properties of b-baryon decay matrix elements (amplitudes) are derived in a nonsymmetric quark model without any use of SU(6), SU(3), or SU(2) (isotopic spin) groups. Equalities between pairs of atrix elements are derived, and Λ–Σ mixing is used to calculate the branching ratio for the transition Λb → Σ0. (paper)
