Description
We discuss here the two-body weak decays of charmed baryons in a simple SU(3) dynamical scheme. Considering the decays B → B'+P in s, t, and u channels and assuming the dominance of nonexotic intermediate states, several decay amplitudes are obtained. We find that the the parity-violating decays in B(3) → B(8)+P(3*), B(3) → D(10) +P(3*), and B(3*) → D(10)+P(8) channels are forbidden independent of the nature of the weak current. We obtain null asymmetries for the weak decays of singlet charmed isobar Ω/sup asterisk++/3
