Rare and forbidden decay of charm mesons at CLEO-c and BES-III

Abstract

This paper presents the results of searches for the flavor-changing neutral current, lepton-numberviolating and lepton-flavor-violating processes in the charm mesons decays. Recent results from charged D mesons decays to final states with dielectrons from CLEO-c are reported. The prospects of the searches for the rare charm decays at BES-III are also discussed.
