Astro 2020 Science White Paper: Cosmic-ray Antinuclei as Messengers for Dark Matter

Abstract
- The origin of dark matter is a driving question of modern physics. Low-energy antideuterons provide a "smoking gun" signature of dark matter annihilation or decay, essentially free of astrophysical background. Low-energy antiprotons are a vital partner for this analysis, and low-energy antihelium could provide further discovery space for new physics. In the coming decade, AMS-02 will continue accumulating the large statistics and systematic understanding necessary for it to probe rare antinuclei signatures, and GAPS, which is the first experiment optimized specifically for low-energy cosmic antinuclei, will begin several Antarctic balloon campaigns. The connection of cosmic-ray antinuclei and dark matter is reviewed and the outlook in light of experimental progress is presented.<br />Comment: 12 pages, 2 figures, Science White Paper submitted to the Astro2020 Decadal Survey. arXiv admin note: text overlap with arXiv:2002.04163
