Abstract

Based on 106 million $ψ (3686)$ events collected with the BESIII detector at the BEPCII, the decay $ψ (3686) \to ω K \bar{K} π$ is studied. Enhancements around $1.44 GeV / c^{2}$ and the $f_{1} (1285)$ are observed in the mass spectrum of $K \bar{K} π$ , and the corresponding branching fraction (upper limit) is measured, as well as the branching fractions of $ψ (3686) \to ω K^{* +} K^{-} + c . c .$ and $ψ (3686) \to ω {\bar{K}}^{* 0} K^{0} + c . c .$ , all for the first time.
