Query: Quark model relations for b-baryon decay   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
$\Lambda-\Sigma$ mixing is used to calculate the branching ratio for the
transition $\Lambda_b\rightarrow \Sigma^0$.
