Search for Rare and Forbidden Decays D^+ --> h^pm e^mp e^+

Abstract

Using 0.8 million D^+D^- pairs collected with the CLEO-c detector at the psi(3770) resonance, we have searched for flavor-changing neutral current and lepton-number-violating decays of D^+ mesons to final states with dielectrons. We find no indication of either, obtaining 90% confidence level upper limits of B(D^+ -> π^+ e^+ e^-) < 7.4 X 10^{-6}$,B(D^{+}->{\pi }^{-}{e}^{+}{e}^{+})<3.6X10^{-6}$, B(D^+ -> K^+ e^+ e^-) < 6.2 X 10^{-6}$,andB(D^{+}->K^{-}{e}^{+}{e}^{+})<4.5X10^{-6}$.
