Contribution

First analysis of CLEO-c data at psi(3770) providing precise measurements of D meson decays, enhancing existing knowledge with new experimental results.

Findings

Results have better or comparable precision to 2004 world averages.

First data set analysis from CLEO-c at psi(3770).

Initial measurements of leptonic and semileptonic D decays.

Abstract

We report the initial results from CLEO-c based on the 55.8/pb data obtained at the psi(3770) resonance last year. We give a concise summary of the various CLEO-c analyses on leptonic and semileptonic decays of neutral and charged D mesons. The data used for this report is the first part of the psi(3770) data sets to be collected during next several years using the Cornell Electron Storage Ring. Most of the results shown here have already better or the same level of precision compared to the 2004 world averages compiled by the Particle Data Group.
