Description

The BESIII experiment has collected 10 billion $J/ψ$ events and 2.7 billion $ψ(3686)$ events. The huge charmonium data samples allow us to search for rare decay processes allowed in the standard model and new physics beyond the standard model.
In this talk, we report the search for charged lepton flavor violation process ψ(3686)→eμ, charmonium weak decay processes $J/ψ→γD^0$, $J/ψ→D^0μ^+μ^-$, $J/ψ→D^0K^{0*}$, $J/ψ→D_s e ν$, $J/ψ→D_sρ/D_sπ$ and $ψ(3686)→D_sρ/D_sπ$. The search for Bose symmetry violation processes $J/ψ→K_SK_S$ and $ψ(3686)→K_SK_S$ will also be presented.
