Abstract
Dark matter particles could be the major component of the haloes of galaxies. Their mutual annihilations or decays would produce an indirect signature under the form of high-energy cosmic-rays. The focus of this presentation is on antimatter species, a component so rare that any excess over the backgound should be easily detected. After a recap on Galactic propagation, I will discuss positrons, antiprotons and anti-nuclei. For each of these species, anomalies have been reported. The antiproton excess, for instance, is currently a hot topic. Alas, it does not resist a correct treatment of theoretical and data errors.

Report
The antimatter component in the cosmic ray spectrum and the measurement of the magnetic halo in the Milky Way is a relevant topic in High-Energy physics, dark matter, and astroparticle physics. I recommend the proceeding for publication.
