Abstract

Using a data sample with an integrated luminosity of $3.9{\mathrm{fb}}^{\mathrm{\ensuremath{-}}1}$ collected in ${e}^{+}{e}^{\ensuremath{-}}$ annihilation with the CLEO-II detector at the Cornell Electron Storage Ring, we have measured the branching ratios for the decay modes ${D}_{s}^{+}\ensuremath{\rightarrow}(\ensuremath{\eta},{\ensuremath{\eta}}^{\ensuremath{'}}){\ensuremath{\pi}}^{+}$ and ${D}_{s}^{+}\ensuremath{\rightarrow}(\ensuremath{\eta},{\ensuremath{\eta}}^{\ensuremath{'}}){\ensuremath{\rho}}^{+}$ relative to ${D}_{s}^{+}\ensuremath{\rightarrow}\ensuremath{\varphi}{\ensuremath{\pi}}^{+}.$ These decay modes are among the most common hadronic decays of the ${D}_{s}^{+},$ and can be related by factorization to the semileptonic decays ${D}_{s}^{+}\ensuremath{\rightarrow}(\ensuremath{\eta},{\ensuremath{\eta}}^{\ensuremath{'}}){\mathcal{l}}^{+}{\ensuremath{\nu}}_{l}.$ The results obtained are compared with previous CLEO results and with the branching ratios measured for the related semileptonic decays. We also report results on the Cabibbo-suppressed decays of the ${D}^{+}$ to the same final states.
