Dark matter from Monogem

Search for boosted keV-MeV light dark matter particles from evaporating primordial black holes at the CDEX-10 experiment

“…Considering the Migdal effect, the sensitivity in the low m χ ∼ O(100 MeV) range can be significantly improved [30][31][32][33]. Further, when χ are scattered and accelerated to (semi)relativistic velocities by cosmic ray nuclei [34][35][36][37][38][39][40], blazar jet protons [41], and supernova remnants [42], χ with m χ ≲ O(1 GeV) can be detected.…”
