Abstract

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_sD_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→ D⁰μ⁺μ^-, J/ψ→ D⁰γ and D_s⁺→ h(h')e⁺e^-. The search for J/ψ weak decays containing a D meson, J/ψ→ D_s^-π⁺, and J/ψ→ D_s^-ρ⁺ will also be presented.
