Abstract
We investigate two-body Cabibbo-angle enhanced weak decays of charmed baryo ns into octet baryon and pseudoscalar meson in the current algebra framewor k with inclusion of the factorization terms which are evaluated using the H QET guided baryonic form factors. We obtain the branching ratios and asymme try 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 a lso investigated.
