Abstract

Beauty and charm $e^{+} e^{-}$ factories running at resonance thresholds have unique capabilities for studies of the production of light dark matter particles in the decays of $B_{q} (D)$ meson pairs. We provide a comprehensive study of light dark matter production in heavy meson decays with missing energy $E̸$ in the final state, such as $B_{q} (D^{0}) \to E̸$ and $B_{q} (D^{0}) \to γ E̸$ . We argue that such transitions can be studied at the current flavor factories (and future superflavor factories) by tagging the missing-energy decays with $B (D^{0})$ decays “on the other side.”

While no elementary particle with properties appropriate for DM exists in the SM, it does not mean that new physics is required to explain DM. For example, DM could exist in the form of small primordial black holes. For more details see C. Bambi, A. D. Dolgov, and A. A. Petrov, Phys. Lett. B 670, 174 (2008); 681, 504(E) (2009); P. H.
