Many scenarios of physics beyond the Standard Model predict dark sectors containing new particles interacting only feebly with ordinary matter. Collider searches for these scenarios have largely focused on identifying signatures of new mediators, leaving much of the dark sector structure unexplored. We investigate the existence of a light dark-matter bound state, the darkonium, $\Upsilon_D$),...
Belle has unique reach for a broad class of models that postulate the existence of dark matter particles with MeV—GeV masses. This talk presents recent world-leading physics results from Belle II searches for dark Higgstrahlung. ALPs and Z'.
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...
