Description
Abstract: The AMS-02 and PAMELA instruments published recently two important results for our understanding of galactic cosmic-ray propagation. The AMS-02 experiment measured the positron fraction up to 350 GeV, confirming and extending the rise observed by PAMELA and Fermi-LAT in a wider energy range and with greater precision. The PAMELA Collaboration released the proton fluxes measured year by year from 2006 to 2009. I will discuss how these data improve our knowledge on propagation of cosmic rays in the galaxy and in the solar system and show that a coherent picture is emerging.
