N2 - Based on a sample of (2712.4 ± 14.3) × 106ψ(3686) events collected with the BESIII detector, a partial wave analysis of the decay ψ3686→ΛΣ¯0π0 + c.c. is performed to investigate Λ* and Σ* resonances in the π0Σ¯0 and π0Λ invariant mass distributions. Significant contributions are found from the Λ(1405), Λ(1520), Λ(1600), Λ(1670), Λ(1690), Λ(1800), Λ(1890), Λ(2325), Σ(1385), Σ(1660), Σ(1670), Σ(1750), and Σ(1910). The masses, widths, and production branching fractions for each component are determined. In addition, the branching fraction of ψ3686→ΛΣ¯0π0 + c.c. is measured to be (1.544 ± 0.013 ± 0.071) × 10−4 for the first time, where the first uncertainty is statistical and the second systematic.
