A model to explain angular distributions of $J / ψ$ and $ψ (2 S)$ decays into $Λ Λ$ and $Σ^{0} Σ^{0}$

M. Alekseev, A. Amoroso, R. Baldini Ferroli +28

BESIII data show a particular angular distribution for the decay of the $J / ψ$ and $ψ (2 S)$ mesons into the hyperons $Λ Λ$ and $Σ^{0} Σ^{0}$ . More in details the angular…
