Measurement of the branching fraction for $\psi (3686)\to \omega K_S^0{K}_S^0$

Abstract

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