Exploring sub-GeV Dark Matter Physics with Cosmic Ray and Future Telescopes

Guansen Wang, Bing-Yu Su, Lei Zu +1

If sub-GeV Dark matter(DM) annihilates to the charged particles such as $e^{+}{e}^{-}$, ${\mu }^{+}{\mu }^{-}$, or ${\pi }^{+}{\pi }^{-}$, it generates an additional source of electrons and positrons in the cosm…
