Antinuclei from DM annihilation
The annihilations of Dark Matter particles in the Galaxy can produce fluxes of antimatter, in particular antiprotons, antideuterons and possibly even nuclei of anti-helium. Since the astrophysical yield of these same species is rather well under control, the detection of an anomaly in these channels will constitute a clear signature for Dark Matter. I will discuss the mechanisms of production of antinuclei from DM, their propagation in the Galaxy and the detection strategies. I will pay some special attention to the antiproton data recently released by AMS-02, discussing which conclusions can be drawn and which ones can not (and should not) be drawn.
