Abstract

This analysis searches for a new type of rare decay of the charmed mesons,

which would provide direct evidence for the presence of Fock states inside

hadrons.

We use 586pb of e+e- collisions at the Cornell Electron Storage

Ring (CESR), at \sqrt{s}=4.17 GeV, recorded with the Cleo-c detector.

A limit on the branching ratio Ds to omega e nu is found, at 0.231\%

(95\% C.L.).
