Charmed baryon Omega(0)(c) -> Omega - l(+)nu(1) and Omega(0)(c) -> Omega(-)(c) pi(+) (rho(+)) decays in light cone sum rules

The semileptonic Omega(0)(c). Omega(-)l nu and nonleptonic Omega(0)(c) -> Omega(-) pi(+), Omega(0)(c) -> Omega-.thorn decays of the charmed Oc baryon are studied within the light cone sum rules. The form factors responsible for Omega c -> Omega transitions are calculated using the distribution amplitudes of the Omega c baryon. With the obtained form factors, the branching ratios of Omega(0)(c) -> Omega-l+nu(l), Omega(0)(c) -> Omega(-) pi(+), and Omega(0)(c) -> Omega(-)rho(+) decays are estimated. The results are compared with Belle data as well as the findings of other approaches.
