The Antideuteron Spectrum<br />

No cosmic-ray antideuterons have been detected yet, only upper<br />

limits exist<br />

Antideuterons may form by coalescence of an antineutron-antiproton<br />

pair that lies very closely together in momentum space<br />

Spectral shape of background and dark matter signal are different at<br />

low energies<br />

Detection of a single antideuteron at low energies could provide<br />

important clue<br />
