Measurement of the branching ratios for the decays of Ds + to ηπ+, η′π+, ηρ+, and η′ρ+

Journal article

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 Ds+→(η,η′)π+ and Ds+→(η,η′)ρ+ relative to Ds+→φ+. These decay modes are among the most common hadronic decays of the Ds+ , and can be related by factorization to the semileptonic decays Ds+ →(η,η′)ℓ+νl. 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. © 1998 The American Physical Society.
