Dark matter searches with cosmic rays in the light of AMS-02




The efforts to uncover the nature of dark matter, the invisible component permeating the Cosmos, have been, so far, unsuccessful. A complementary mean to investigate dark mat ter is through indirect searches via cosmic rays. In particular, in the talk, I will focus on the case of cosmic-ray antiprotons, which have been recently measured by the AMS-02 experiment with high precision. I will discuss the results of a recent analysis where we use the new data and we interpret them within the framework of a new updated cosmic-ray propagation model consistent with the AMS-02 data. Interestingly, the analysis show a significant hint for the presence of a dark matter particle with mass of about 100 GeV and annihilation cross section close to the thermal relic value. Finally, I will discuss possible systematic effects and the work required to address them.
