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.).
