摘要
The unprecedented precision of AMS-02 data inaugurates a new astroparticle era, where astrophysical uncertainties which affect cosmic-ray (CR) propagation can be greatly reduced, allowing to study anomalies and highlight new phenomena, to corroborate or falsify present dark-matter (DM) theories and to explore a TeV-ish dark-matter scenario. AMS-02 published data, i.e. positrons, electrons, protons and helium fluxes, already give us important information about CR production and propagation mechanisms, hinting at new fundamental physics. Official papers dedicated to secondaries over primaries ratios and antiprotons physics are incoming and will clarify this puzzling landscape and guide us in the dark-matter search.
