Journal of High Energy Physics, 2021(11), 1-20.1029-8479https://doi.org/10.1007/JHEP11(2021)217https://hdl.handle.net/20.500.12713/2318By analyzing 4.48 x 10(8) psi(3686) events collected with the BESIII detector, we observe the decays chi(cJ) -> nK(S)(0) (Lambda) over bar + c.c. (J = 0, 1, 2) for the first time, via the radiative transition psi(3686) -> gamma chi(cJ). The branching fractions are determined to be (6.65 +/- 0.26(stat)+/- 0.41(syst)) x 10(-4), (1.66 +/- 0.12(stat) +/- 0.12(syst)) x 10(-4), and (3.58 +/- 0.16(stat) +/- 0.23(syst)) x 10(-4) for J = 0, 1, and 2, respectively.eninfo:eu-repo/semantics/openAccesse(+)-e(-) ExperimentsArticle11WOS:0007240311000062-s2.0-85120652124Q110.1007/JHEP11(2021)217Q2
