Description
Antideuterons are among the most promising Galactic cosmic-ray- related targets for dark-matter indirect detection, because their primary spectrum is flatter than the standard astrophysical component at low ki- netic energies (E < 2 − 3 GeV/n). We are performing a parameter scan in the supersymmetric (SUSY) parameter space using the SuperBayes pack- age in order to estimate the detection power of future experiments such as AMS-02 and GAPS. The primary antideuterons produced from pair annihilation of dark matter particles in the halo of our Galaxy is esti- mated by the latest DarkSusy package. For the calculation of the stan- dard astrophysical background signal, including secondary and tertiary antideuterons, the USINE propagation package is used. The latter deals with the propagation of Galactic cosmic-ray nuclei (all existing nuclei) and antinuclei (antiprotons and antideuterons) in various models (Leaky Box and diffusion models). Preliminary results will be presented.
