dc.description.abstractBased on (2712.4±14.3)×106 e+e-→ψ(3686) events collected with the BESIII detector operating at the BEPCII Collider, we report the first evidence of χc0→ΛΛ¯φ decays and the first observation of χc1,2→ΛΛ¯φ decays, with significances of 4.1σ, 11.3σ and 13.0σ, respectively. The decay branching fractions of χc0,1,2→ΛΛ¯φ are measured to be (2.99±1.24±0.19)×10-5, (6.01±0.90±0.40)×10-5, and (7.13±0.81±0.36)×10-5, where the first uncertainties are statistical and the second systematic. No obvious enhancement near the ΛΛ¯ production threshold or excited Λ state is found in the Λφ (or Λ¯φ) system.
