92. Search for darkonium in $e^+e^-$ collisions at $BABAR$

Bertrand Echenard (Califortnia Institute of Technology)

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, $\Upsilon_D$),...

28. Recent dark sector results at Belle II

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'.

18. Dark sector search at BESIII

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...

59. Search for an Axion-Like Particle in B meson decays at BABAR

Axion-like particles (ALPs) are predicted in many extensions of the Standard Model, and their masses can naturally be well below the electroweak scale. In the presence of couplings to electroweak bosons, these particles could be emitted in flavor-changing B meson decays. We present a search for an axion-like particle (ALP), $a$, produced in the Flavor-Changing Neutral-Current decay $B\to Ka$,...
