First observation of the isospin violating decay $J / ψ \to Λ Σ ˉ^{0} + c . c .$

M. Ablikim, M. N. Achasov, D. J. Ambrose +353

Using a sample of $(225.2 \pm 2.8) \times 1 0^{6}$ $J / ψ$ events collected with the BESIII detector, we present results of a study of $J / ψ \to γ Λ Λ ˉ$ and report the first observ…
