Search for Rare and Forbidden Decays of D mesons to Final States with Electrons

Abstract

Using the CLEO-c detector and a data sample of 0.8 million D+D- pairs at the Psi(3770) a search has been performed for flavor changing neutral current and lepton number violating decays of D+ mesons to final states with dielectrons. No signals are observed and 90% confidence limits are set for specific decay modes in the range of a few times ten to the minus six.
