A 0.233 g silicon athermal phonon detector with 361.5 MeV/c² rms resolution sets the strongest direct-detection limits on dark matter-nucleon cross sections for masses 44–87 MeV/c² after 12 hours of exposure.
Boosted sub-GeV dark matter from atmospheric cosmic ray bremsstrahlung can be probed by direct detection and neutrino experiments, with enhanced sensitivity near vector mediator resonances.
In a dark-photon-mediated Dirac fermionic DM model, only narrow resonant regions with small dark-sector coupling allow the candidate to saturate the full relic density while evading current direct and indirect detection bounds.
