Abstract

By analyzing 4.48 × 10⁸ψ(3686) events collected with the BESIII detector, we observe the decays χ_cJ → nKS0Λ¯ + c.c. (J = 0, 1, 2) for the first time, via the radiative transition ψ(3686) → γχ_cJ. The branching fractions are determined to be (6.65 ± 0.26_stat ± 0.41_syst) × 10⁻⁴, (1.66 ± 0.12_stat ± 0.12_syst) × 10⁻⁴, and (3.58 ± 0.16_stat ± 0.23_syst) × 10⁻⁴ for J = 0, 1, and 2, respectively.
