Abstract:
By analyzing 4 . 48 × 10 8 ψ (3686) events collected with the BESIII detector, we observe the decays χ cJ → $$ {nK}_S^0\overline{\Lambda} $$ nK S 0 Λ ¯ + 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.
