Antimatter from supersymmetric dark matter
Abstract
Description
We propose low-energy antideuterons in cosmic rays as a new possible signature for indirect detection of supersymmetric dark matter.
Since the energy spectrum of the antiproton secondary component is still spoilt by considerable theoretical uncertainties, looking for low-energy antideuterons seems a plausible alternative.
We apply our calculation to the AMS experiment, when mounted on the International Spatial Station. If a few low-energy antideuterons will be discovered by AMS, this should be seriously taken as a clue for the existence of relic, massive neutralinos in the dark halo of our Galaxy.
