Description
The BESIII experiment is a symmetric $e^+e^-$ collider operating at c.m. energy from 2 to $4.95~\rm GeV$. With the world’s largest data set of $J/\psi$ (10 Billion), $\psi(2S)$ (2.6 Billion), and about $25 fb^{-1}$ scan data from 3.77 to $4.95~\rm GeV$, we are able search various dark sectors produced in $e^+e^-$ annihilation and meson decay processes. In this talk, we report the recent search for dark photon candidate in $J/\psi \to e^+e^-\eta/\eta^\prime$, $e^+e^- \to \gamma A^\prime \to \mu^+\mu^-/e^+e^-$, $e^+e^- \to \gamma+ invisible$ process. In addition, a possible light Higgs $A_0$ in $J/\psi \to \gamma A_0$ process is also searched.
