论文摘要
B-Baryon衰减矩阵元件（振幅）的性质已在非对称夸克模型中得出，而无需使用SU（6），SU（3）或SU（2）（同位素自旋）组。得出了振幅对之间的平等性，并使用$λ-σ$混合来计算过渡$λ_b\rightarrowσ^0 $的分支比率。
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 $Λ-Σ$ mixing is used to calculate the branching ratio for the transition $Λ_b\rightarrow Σ^0$.
