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. ",
