N2 - Using (27.12±0.14)×108 ψ(3686) events collected with the BESIII detector, we present the first observation of the decays χcJ→ΛΛ¯ω, where J=0, 1, 2, with statistical significances of 11.7σ, 11.2σ, and 11.8σ. The branching fractions of these decays are determined to be B(χc0→ΛΛ¯ω)=(2.37±0.22±0.25)×10-4, B(χc1→ΛΛ¯ω)=(1.01±0.10±0.11)×10-4, and B(χc2→ΛΛ¯ω)=(1.40±0.13±0.17)×10-4, where the first uncertainties are statistical and the second are systematic. We observe no clear intermediate structures.
