Study of $J/\psi \to \omega K^{+}{K}^{-}$

Abstract

New data are presented on $J/\psi \to \omega K^{+}{K}^{-}$ from a sample of 58M $J/\psi$ events in the upgraded BES II detector at the BEPC. There is a conspicuous signal for $f_0(1710)\to K^{+}{K}^{-}$ and a peak at higher mass which may be fitted with $f_2(2150)\to K\bar{K}$. From a combined analysis with $\omega {\pi }^{+}{\pi }^{-}$ data, the branching ratio $BR(f_0(1710)\to \pi \pi )/BR(f_0(1710)\to K\bar{K})$ is $<0.11$ at the 95% confidence level.
