Ds+decays to ηρ+, η’ρ+, and φρ+

We have observed the previously unseen \ensuremath{\eta}${\mathrm{\ensuremath{\rho}}}^{+}$ and \ensuremath{\eta}'${\mathrm{\ensuremath{\rho}}}^{+}$ decay model of the ${\mathit{D}}_{\mathit{s}}^{+}$, and measured branching ratios relative to the \ensuremath{\varphi}${\mathrm{\ensuremath{\pi}}}^{+}$ mode of 2.86\ifmmode\pm\else\textpm\fi{}0.${38}_{\mathrm{\ensuremath{-}}0.38}^{+0.36}$ and 3.44\ifmmode\pm\else\textpm\fi{}0.${62}_{\mathrm{\ensuremath{-}}0.46}^{+0.44}$, respectively. In addition, the relative branching ratio for the decay into \ensuremath{\varphi}${\mathrm{\ensuremath{\rho}}}^{+}$ is measured as 1.86\ifmmode\pm\else\textpm\fi{}0.${26}_{\mathrm{\ensuremath{-}}0.40}^{+0.29}$. Combining these new measurements with previous results and those in the preceding Letter, we account for \ensuremath{\approxeq}(79\ifmmode\pm\else\textpm\fi{}26)% of ${\mathit{D}}_{\mathit{s}}$ decays.
