Description
The BESIII experiment is taking data at symmetric e+e- collider operating at the center of mass
energies from 2.0 to 4.95 GeV. With the world’s largest on-threshold production data
set of $J/\psi$ (10 billion), $\psi(3686)$ (2.6 billion), and 20 $fb^{-1}$ of $\psi(3770)$ decaying
into D meson pairs, we are able to search for various dark sectors candidates produced in e+e-
annihilation and meson decay processes. In this talk, we report the search for BSM
particles in $\Sigma$ decay and Axion-like particle search with $J/\psi$ data. The search
for massless dark photon through the charm FCNC process $D^0 \to \omega \gamma’$ and
$D^0 \to \gamma \gamma’$, and $K_s^0$ invisible decay will also be presented.
