Abstract

We have searched for the inclusive reaction using a tagged sample of 68 D produced in the reaction e+e-*at a center-of-mass energy of 4.14 GeV. The tagged sample consists of the decays Ds+ Ds+K» *0K+, and Ds+K» K+. We determine B(Ds+e+X)=0.05-0.05+0.05±0.02, which corresponds to a limit of B(Ds+e+X)<0.20, at the 90% confidence level.
