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...

The Belle and Belle II experiment have collected samples of $e^+e^-$ collision data at center-of-mass energies near the $\Upsilon(nS)$ resonances. These data have constrained kinematics and low multiplicity, which allow searches for dark sector particles in the mass range from a few MeV to 10 GeV. We present new searches in a $600~\mathrm{fb}^{-1}$ sample collected by Belle II, including...
