Searching for cosmic antihelium nuclei with the GAPS experiment

Abstract: At low energies, cosmic antideuterons and antihelium provide an ultra-low background signature of dark matter annihilation, decay, and other beyond the Standard Model phenomena. The General Antiparticle Spectrometer (GAPS) is an Antarctic balloon experiment designed to search for lowenergy (0.1−0.3 GeV/ ) antinuclei, and is planned to launch in the austral summer of 2022. While optimized for an antideuteron search, GAPS also has unprecedented capabilites for the detection of low-energy antihelium nuclei, utili… Show more

“…The General Antiparticle Spectrometer (GAPS) is an experiment designed to detect low energy ( 0.25 GeV/n) cosmic-ray antiprotons and antinuclei, see [49,51,52]. The antideuteron channel is particularly exciting for DM searches since it is almost background free at low energies.…”
