A Study of Weak Mesonic Decays of $\Lambda_c$ and $\Xi_c$ Baryons on the Basis of HQET Results

Abstract

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 $\Lambda_c^+$, $\Xi_c^+$ and $\Xi_c^0$ baryons. Sensitivity of the flavor dependence of the spatial wavefunction overlap on the branching ratios and asymmetry parameters is also investigated.
