| contents | Search for new physics with charm rare decays at BESIII. The BESIII experiment has collected 2.6 billion $ψ(3686)$ events, 10 billion $J/ψ$ events, $20 fb^{-1}$ D meson pairs at 3.773 GeV, and $7.33 fb^{-1}~D_{s}D_{s}^{*}$ events from 4.128 to 4.226 GeV. The huge data samples allow us to search for rare processes in charm hadron decays. In this paper, we report the FCNC decay in $J/ψ\to D^0μ^+μ^-$, $J/ψ\to D^0γ$ and $D_{s}^{+}\to h(h')e^+e^-$. The search for $J/ψ$ weak decays containing a D meson, $J/ψ\to D_{s}^{-}π^{+}$, and $J/ψ\to D_{s}^{-}ρ^{+}$ will also be presented. |
