Indirect detection of dark matter WIMP annihilation by satellite experiments (Fermi-LAT or AMS-02), including a new kind of dark matter candidate with well defined mass and couplings

Fermi-LAT, AMS-02, and other experiments have observed intriguing signals involving positrons, antiprotons, and gamma ray photons, but so far all of these can potentially be attributed to astrophysical sources rather than dark matter annihilation. I.e., there is as yet no definitive evidence of dark matter in these signals. Here we discuss the potential of these experiments for seeing an unambiguous signal of dark matter annihilation, with emphasis on both neutralinos and a new kind of dark matter candidate with well-defined mass and couplings [1]. These new particles are
in many respects ideal dark matter candidates. However, their couplings are in a sense
weaker than those expected for the most popular of the previous candidates, and this
fact may explain why dark matter particles have so far eluded detection. The theory
that predicts these new particles also unambiguously predicts supersymmetry and thus
a plethora of new neutral and charged particles, and new physics, to be discovered in the foreseeable future.
