Description
The BESIII experiment has collected 10 billion J/ψ events, 2.6 billion ψ(3686) events, 20 $fb^{-1}$ of D meson pairs at 3.773 GeV, and 7.33 $fb^{-1}$ of $D_sD_s^*$ events from 4.128 to 4.226 GeV. The huge data samples allow us to search for new physics beyond the standard model with rare decay processes in charm data. In this talk, we report the search for baryon number violation processes J/ψ→pe and J/ψ→$\Lambda \bar{\Lambda}$, lepton number violation processes Φ/ω/η→π+π+e-e-, $D_s^+$→$h^-h^0e^+e^+$, Ξ-→Σ$^+e^-e^-$ and J/ψ→$K^+K^+e^-e^-$, lepton flavor violation process ψ(3686)→eμ. The search for new physics with J/ψ weak decay J/ψ→γ$D^0$, J/ψ→$D^0μ^+μ^-$, J/ψ→$D^0K^{0*}$, J/ψ→$D_sρ/D_sπ$ and J/ψ→$D_seν$ will also be presented.
