Funded by SCOAP3.The semileptonic ωc0→ω-lν and nonleptonic ωc0→ω-π+, ωc0→ω-ρ+ decays of the charmed ωc baryon are studied within the light cone sum rules. The form factors responsible for ωc→ω transitions are calculated using the distribution amplitudes of the ωc baryon. With the obtained form factors, the branching ratios of ωc0→ω-l+νl, ωc0→ω-π+, and ωc0→ω-ρ+ decays are estimated. The results are compared with Belle data as well as the findings of other approaches.
