W exchange contributions in hadronic decays of charmed baryons

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 ${\Xi }_c^0\to {\Xi }^{\ast -}{\pi }^{+},{\Sigma }^{\ast +}{K}^{-},{\Omega }^{-}{K}^{+}$ and ${\Lambda }_c^{+}\to {\Sigma }^0{\pi }^{+},{\Xi }^0{K}^{+}$, ${\Xi }_c^0\to {\Sigma }^{+}{K}^{-}$.
