在当前的代数框架下研究了粲重子到八重态重子和赝标介子的两体Cabibbo角增强的弱衰变，其中包含了使用HQET引导的重子形状因子计算的因子分解项.我们得到了，$\Xi^c^+$和重子的各种Cabibbo增强衰变的分支比和不对称参数。还研究了空间波函数重叠对分支比和不对称参数的风味依赖性的敏感性。
We investigate two-body Cabibbo-angle enhanced weak decays of charmed baryons into octet baryon and pseudoscalar meson in the current algebra framework with inclusion of the factorization terms which are evaluated using the HQET guided baryonic form factors. We obtain the branching ratios and asymmetry parameters for various Cabibbo-enhanced decays of, $\Xi^c^+$ andbaryons. Sensitivity of the flavor dependence of the spatial wavefunction overlap on the branching ratios and asymmetry parameters is also investigated.
