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 Λ b → Σ 0 .

B重子衰变的夸克模型关系

b重子衰变矩阵元素(振幅)的属性是在不对称夸克模型中导出的,无需使用SU(6),SU(3)或SU(2)(同位素自旋)基团。导出成对的矩阵元素之间的等式,并使用Λ-Σ混合来计算过渡Λb→Σ0的分支比。
