Scientific paper

Searches for low-energy antideuterons appear as a plausible alternative to antiprotons to indirectly probe for the existence of supersymmetric relics in the galactic halo. Above a few GeV/n, a dozen spallation antideuterons should be collected by the future AMS experiment on board ISS. For energies less than ~ 3 GeV/n, the Dbar spallation component becomes negligible and may be supplanted by a possible supersymmetric signal. If a few low-energy antideuterons are discovered, this should be seriously taken as a clue for the existence of massive neutralinos in our Galaxy
