The Cabibbo-favored hadronic weak decays of the ${\mathrm{\Xi }}_c$ in the quark model

The Cabibbo-favored hadronic weak decay of the ${\mathrm{\Xi }}_c^{+}\to {\mathrm{\Xi }}^0{\pi }^{+}$, ${\mathrm{\Xi }}_c^0\to {\mathrm{\Xi }}^{-}{\pi }^{+}$, ${\mathrm{\Xi }}_c^0\to {\mathrm{\Xi }}^0{\pi }^0$, ${\mathrm{\Xi }}_c^0\to {\mathrm{\Xi }}^0{\eta }^{{(}^{\mathrm{\prime }})}$ and ${\mathrm{\Xi }}_c^0\to {\mathrm{\Xi }}^{+}{K}^{-}$ are studied in the non-relativistic constituent quark model. By analyzing their decay mechanisms at the quark level we show that the pole terms are essential for understanding the transition dynamics in addition to the usually considered direct meson emission process and color suppressed process in the charmed baryon hadronic weak decays. The experimentally measurable asymmetry parameters are also predicted in order to further pin down the decay mechanism.
