Description
The BESIII experiment is taking dat at 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 $fb^{-1}$ of 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 $K_S^0$ invisible decay, search for the massless dark photon with charm FCNC process $D^0→ωγ’$ and $D^0→γγ’$, search for the dark baryon decay in $Ξ^-→π^-$ + invisible, search for J/ψ→Φ + invisible, and search for X(17) with $ψ(3686)→X(17)χ_c^0$ and $ψ(3686)→γχ_c^0->γX(17)J/ψ$.
