QCD sum rules study on weak decays ${\Omega }_c^0\to {\Omega }^{-}({\pi }^{+},{\rho }^{+},l^{+}{\nu }_l)$

Yu-Ji Shi, Jun Zeng

We study the weak decays of the charmed baryon ${\Omega }_c^0$ to the ${\Omega }^{-}$ baryon within the framework of QCD sum rules. A three-point correlation function is defined for calculating eigh…
