Abstract

Using a data sample with an integrated luminosity of 3.9 fb^-1 collected in e⁺e^- annihilation with the CLEO-II detector at the Cornell Electron Storage Ring, we have measured the branching ratios for the decay modes D_s⁺ → (η, η′)π⁺ and D_s⁺ → (η, η′)ρ⁺ relative to D_s⁺ → φπ⁺. 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⁺ → (η, η′)ℓ⁺ν₁ . 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.
