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

Journal article

Using a data sample with an integrated luminosity of 3.9 fb 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 → (η,η′)π and D →(η,η′)ρ relative to D → φπ . These decay modes are among the most common hadronic decays of the D , and can be related by factorization to the semileptonic decays D →(η,η′)ℓ ν . 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.
