Abstract

$K^{+} K^{-} π^{+} π^{-} π^{0}$ final states are studied using a sample of $14 \times 10^{6}$ $ψ (2 S)$ decays collected with the Beijing Spectrometer (BESII) at the Beijing Electron-Positron Collider. The branching fractions of $ψ (2 S)$ decays to $K^{+} K^{-} π^{+} π^{-} π^{0}$ , $ω K^{+} K^{-}$ , $ω f_{0} (1710)$ , $K^{*} (892)^{0} K^{-} π^{+} π^{0} + c . c .$ , $K^{*} (892)^{+} K^{-} π^{+} π^{-} + c . c .$ , $K^{*} (892)^{+} K^{-} ρ^{0} + c . c .$ and $K^{*} (892)^{0} K^{-} ρ^{+} + c . c .$ are determined. The first two agree with previous measurements, and the last five are first measurements.

The branching fraction of $B (J / ψ \to ω K^{+} K^{-})$ is calculated using the numbers in this paper, the total error for $ψ (2 S) \to ω f_{0} (1710)$ is 19.7% and the $f_{0} (1710)$ intensity is $(38 \pm 6) %$ of the data, where the error is almost entirely systematic. So we estimated the systematic error for $J / ψ \to ω K^{+} K^{-}$ is 11.8%.
