Abstract

The nonleptonic decays of $\Xi_c^0$ and $\Lambda_c^+$ that are dominated by $W$-exchange are studied. In particular, we anlayse the decay modes $\Xi_c^0 \rightarrow \Xi^{*-} \pi^+, \Sigma^{*+}K^-, \Omega^-K^+$ and $\Lambda_c^+\rightarrow \Sigma^0\pi^+, \Xi^0 K^+$, $\Xi^0_c\rightarrow \Sigma^+K^-$.
