Abstract
We calculate the exclusive semi-leptonic charm baryon decays of the lowest lying charm baryon states into the ground state strangeness baryons using the covariant spectator quark model approach. We present results on rates,q 2- andE l -spectra as well as on the angular decay distribution in the cascade decay\(\Omega _c \to \Omega ( \to \Xi \pi ,\Lambda {\rm K})\).
