The isospin-violating J/ψ→ΛΛ̄π⁰ decay is shown to selectively produce the dynamically-generated Σ(1430) resonance while suppressing the conventional Σ(1385) state, matching limited BESIII data.

A vector-meson molecular model predicts a0(1710) should show as a clear peak near 1.8 GeV in J/psi -> rho+ rho- omega and J/psi -> gamma rho0 omega mass distributions.
The Ξ(1690), generated from S-wave meson-baryon interactions, is required to describe the BESIII Λ-bar K⁰, Ξ⁰ K⁰ and Λ-bar Ξ⁰ mass distributions in J/ψ decay.
Analysis of J/ψ → Λ π Σ-bar finds Σ(1385) and Σ(1430) signals but shows the Σ(1380) is unnecessary when π Σ-bar interactions are accounted for.
Theoretical calculation of ψ(3686) → Λ Λ̄ η decay shows Λ(1670) peaks in ηΛ and ηΛ̄ distributions using two SU(3) flavor structures and final-state interactions, with one free parameter fitting data and supporting a molecular picture for the resonance.
