Experimental study of $ψ(2S)$ decays to $\K^+ K^- π^+ π^- π^0$ final states
Abstract
Description
$K^+K^-π^+π^-π^0$ final states are studied using a sample of $14\times10^6$ $ψ(2S)$ decays collected with the Beijing Spectrometer (BESII) at the Beijing Electron-Position Collider. The branching fractions of $ψ(2S)$ decays to $ K^+K^-π^+π^-π^0$, $ωK^+ K^-$, $ωf_0(1710)$, $ K^{\ast}(892)^0 K^- π^+π^0+c.c.$, $K^{\ast}(892)^{+} K^- π^+π^- +c.c.$, $K^{\ast}(892)^{+} K^- ρ^0+c.c.$ and $K^{\ast}(892)^0 K^-ρ^+ + c.c.$ are determined. The first two agree with previous measurements, and the last five are first measurements.
