Toward discovering the excited $\Omega$ baryons through nonleptonic weak decays of ${\Omega }_c$

Kai-Lei Wang, Qi-Fang Lü, Ju-Jun Xie +1

The nonleptonic weak decay processes ${\Omega }_c\to \Omega {\pi }^{+}/\Omega (1P){\pi }^{+}/\Omega (1D){\pi }^{+}/\Omega (2S){\pi }^{+}$ are studied using the constituent quark model. The branching fraction of ${\Omega }_c\to \Omega {\pi }^{+}$ is predicted…
