N2 - Using (448.1±2.9)×106 ψ(3686) events collected with the BESIII detector and a single-baryon tagging technique, we present the first observation of the decays ψ(3686)→Ξ(1530)0Ξ¯(1530)0 and Ξ(1530)0Ξ¯0. The branching fractions are measured to be B(ψ(3686)→Ξ(1530)0Ξ¯(1530)0)=(6.77±0.14±0.39)×10-5 and B(ψ(3686)→Ξ(1530)0Ξ¯0)=(0.53±0.04±0.03)×10-5. Here, the first and second uncertainties are statistical and systematic, respectively. In addition, the parameter associated with the angular distribution for the decay ψ(3686)→Ξ(1530)0Ξ¯(1530)0 is determined to be α=0.32±0.19±0.07, in agreement with theoretical predictions within one standard deviation.
