Description
The BESIII experiment is taking data at a 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 particles 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 FCNC process $D^0 \to \omega \gamma’$ and $D^0 \to \gamma \gamma’$, and $K_s^0$ invisible decay will also be presented.
