N2 - Using (10087±44)×106 J/ψ events collected with the BESIII detector, numerous Ξ- and Λ decay asymmetry parameters are simultaneously determined from the process J/ψ→Ξ-Ξ¯+→Λ(pπ-)π-Λ¯(n¯π0)π+ and its charge-conjugate channel. The precisions of αΛ0 for Λ→nπ0 and α¯Λ0 for Λ¯→n¯π0 compared to world averages are improved by factors of 4 and 1.7, respectively.
