Paleo-detectors can achieve high sensitivity to sub-GeV dark matter boosted by cosmic rays and supernovae, covering previously inaccessible parameter space with orders of magnitude better reach than current experiments.
SNO data combined with CANDU reactor production excludes spin-dependent χ-nucleon cross sections above ~10^{-33} cm² for m_χ ≤ 1.5 MeV.
Primordial black hole evaporation generates light fermionic dark matter capable of producing electron recoils in XENONnT, LZ, and PandaX-4T, enabling new constraints on DM-electron interactions after including Earth attenuation effects.
