Description
The BESIII experiment is a symmetric e+e- collider operating at c.m. energy from 2.0 to 4.95 GeV. With the world’s largest threshold production data set of J/ψ (10 billion), ψ(3686) (2.6 billion), and 20 fb^-1 D meson pairs from ψ((3770) decay, we are able to search for various dark sectors produced in e+e- annihilation and meson decay processes. In this talk, we report the search for J/ψ→Φ+invisible, search for Ks0 invisible decay, search for the massless dark photon with charm FCNC process D0→ωγ’ and D0→γγ’, search for the dark scalar mediator with η to π^0 transition, search for the dark baryon decay in Ξ-→π-+invisible, search for the massless particle in Ξ0→Λ+invisible, and search for X(17) with ψ(3686)→X(17)χc0 and ψ(3686)→γχc0->γX(17)J/ψ.
