Experimental study ofψ2Sdecays toK+K−π+π−π0final states

${K}^{+}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}$ final states are studied using a sample of $14\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $\ensuremath{\psi}(2S)$ decays collected with the Beijing Spectrometer (BESII) at the Beijing Electron-Positron Collider. The branching fractions of $\ensuremath{\psi}(2S)$ decays to ${K}^{+}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}$, $\ensuremath{\omega}{K}^{+}{K}^{\ensuremath{-}}$, $\ensuremath{\omega}{f}_{0}(1710)$, ${K}^{*}(892{)}^{0}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{0}+\mathrm{c}.\mathrm{c}.$, ${K}^{*}(892{)}^{+}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}+\mathrm{c}.\mathrm{c}.$, ${K}^{*}(892{)}^{+}{K}^{\ensuremath{-}}{\ensuremath{\rho}}^{0}+\mathrm{c}.\mathrm{c}.$ and ${K}^{*}(892{)}^{0}{K}^{\ensuremath{-}}{\ensuremath{\rho}}^{+}+\mathrm{c}.\mathrm{c}.$ are determined. The first two agree with previous measurements, and the last five are first measurements.
