Abstract

Properties of b-baryon decay matrix elements (amplitudes) have been derived in a nonsymmetric quark model without any use of SU(6), SU(3), or SU(2) (isotopic spin) groups. Equalities between pairs of amplitudes are derived, and ΛΣ\Lambda-\Sigma mixing is used to calculate the branching ratio for the transition ΛbΣ0\Lambda_b\rightarrow \Sigma^0.
