Using direct meson emission, color suppressed, and pole terms in a quark model, the authors reproduce most measured Xi_c decay branching ratios and predict asymmetry parameters, while failing one measured asymmetry sign.

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.

The Cabibbo-favored hadronic weak decays of the $\Xi_c$ in the quark model
Using direct meson emission, color suppressed, and pole terms in a quark model, the authors reproduce most measured Xi_c decay branching ratios and predict asymmetry parameters, while failing one measured asymmetry sign.
