Abstract

Using a sample of (Formula presented) (Formula presented) events collected with the CLEO II detector at the Cornell Electron Storage Ring (CESR), we measure (Formula presented) (Formula presented) and the partial rate (Formula presented) in three bins of (Formula presented) We find (Formula presented) (Formula presented) (Formula presented) (Formula presented) and (Formula presented) Here, (Formula presented) or (Formula presented) but not both, and the errors are statistical, systematic, and theoretical. The method is sensitive primarily to (Formula presented) decays with leptons in the energy range above 2.3 GeV. Averaging with the previously published CLEO results for (Formula presented) we obtain (Formula presented) and (Formula presented) © 2000 The American Physical Society.
