Searches for $D^0$-$\overline{D^0}$ Mixing, Rare Charm and Tau Decays

Abstract

I discuss the results on $D^0$-${\bar{D}}^0$ mixing through hadronic as well as semi-leptonic charm decays, rare flavor-changing neutral currents in the charm sector and the lepton flavor violating $\tau$ decaying to charged lighter leptons. The results from both BABAR and Belle are presented in this review.
