TL;DR

This paper measures the branching ratios of specific Ds meson decay modes using data from e+ e- collisions, providing insights into hadronic decay processes and their relation to semileptonic decays.

Contribution

It presents new measurements of Ds decay branching ratios relative to phi pi, comparing them with previous results and semileptonic decay data.

Findings

Measured branching ratios for Ds -> eta pi, eta' pi, eta rho, eta' rho

Compared hadronic decay ratios with semileptonic decay data

Reported results on Cabibbo-suppressed D+ decays

Abstract

Using a data sample with integrated luminosity of about 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 -> (eta, eta') pi and Ds -> (eta, eta') rho relative to Ds -> phi pi. These decay modes are among the most common hadronic decays of the Ds's and can be related by factorization to the semileptonic decays Ds -> (eta,eta') l nu. 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.
