Abstract: (arXiv)
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^+ -> \pi^+ e^+ e^-) < 7.4 X 10^{-6},B(D+>πe+e+)<3.6X106, B(D^+ -> \pi^- e^+ e^+) < 3.6 X 10^{-6}, B(D^+ -> K^+ e^+ e^-) < 6.2 X 10^{-6},andB(D+>Ke+e+)<4.5X106, and B(D^+ -> K^- e^+ e^+) < 4.5 X 10^{-6}.
