Charmed baryon ${\Omega }_c^0\to {\Omega }^{-}{l}^{+}{\nu }_l$ and ${\Omega }_c^0\to {\Omega }_c^{-}{\pi }^{+}({\rho }^{+})$ decays in light cone sum rules

Abstract

The semileptonic ${\Omega }_c^0\to {\Omega }^{-}l\nu$ and non-leptonic ${\Omega }_c^0\to {\Omega }^{-}{\pi }^{+}$, ${\Omega }_c^0\to {\Omega }^{-}{\rho }^{+}$ decays of charmed ${\Omega }_c$ baryon are studied within the light cone sum rules. The form factors responsible for ${\Omega }_c\to \Omega$ transitions are calculated using the distribution amplitudes of ${\Omega }_c$ baryon. With the obtained form factors, the branching ratios of ${\Omega }_c^0\to {\Omega }^{-}{l}^{+}{\nu }_l$, ${\Omega }_c^0\to {\Omega }^{-}{\pi }^{+}$, and ${\Omega }_c^0\to {\Omega }^{-}{\rho }^{+}$ decays are estimated. The results are compared with Belle data as well as the findings of the other approaches.
