Abstract
We report a search for the decay D0e+e- based on a data sample of 9.6 pb-1 collected at the (3770) resonance with the Mark III detector at the SLAC e+e- storage ring SPEAR. We find no evidence for this flavor-changing weak-neutral-current decay and set an upper limit on the branching ratio of B(D0e+e-)<1.3×10-4 at the 90% confidence level. This limit constrains various extensions of the standard model.
