Observation of $η (2600)$ and Threshold Enhancements in the $Λ Λ ˉ$ System

BESIII Collaboration, M. Ablikim, M. N. Achasov +716

Using $2712.4 \pm 14.3$ million $ψ (3686)$ events collected with the BESIII detector, the $Λ Λ ˉ$ system produced in $ψ (3686)$ radiative decays is studied. A model-independent part…
