Abstract: A search for flavor changing neutral current (FCNC) and lepton number violation (LNV) decays of charmed D mesons is performed using 33pb-1data around Ψ(3770) collected by BESⅡ detector at BEPC. Four decay modes of D0(K0e+e-,Φe+e-,ρ0e+e- and K*0e+e-) and six decay modes of D+(K-e+e+,K+e+e-,π-e+e+, π+e+e-,K*-e+e+ and K*+e+e-) are presented. No evidence is found for the above decays, therefore, the upper limits at 90% confidence level are set. The limits of two D+ decays modes,D+→K*-e+e+和D+→K*+e+e- have not been reported previously.
