Analyzing $(448.1\ifmmode\pm\else\textpm\fi{}2.9)\ifmmode\times\else\texttimes\fi{}{10}^{6}\text{ }\text{ }\ensuremath{\psi}(3686)$ events collected with the BESIII detector at the BEPCII collider, the $\ensuremath{\psi}(3686)\ensuremath{\rightarrow}\ensuremath{\omega}{K}_{S}^{0}{K}_{S}^{0}$ decay is observed for the first time. The branching fraction for this decay is determined to be ${\mathcal{B}}_{\ensuremath{\psi}(3686)\ensuremath{\rightarrow}\ensuremath{\omega}{K}_{S}^{0}{K}_{S}^{0}}=(7.04\ifmmode\pm\else\textpm\fi{}0.39\ifmmode\pm\else\textpm\fi{}0.36)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}$, where the first uncertainty is statistical and the …
