Reconstruction of antinucleus-annihilation events in the GAPS experiment
The General Antiparticle Spectrometer (GAPS) experiment is designed to detect low-energy (< 0.25 GeV/n) cosmic-ray antinuclei as indirect signatures of dark matter. Several beyondthe-standard-model scenarios predict a large antideuteron flux due to dark matter decay or annihilation compared to th...
