  2. 1. Measurements of cosmic ray antiprotons with PAMELA and studies of propagation models

    Author : Juan Wu; Mark Pearce; Fiorenza Donato; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cosmic ray; PAMELA; antiproton flux; propagation;

    Abstract : Studying the acceleration and propagation mechanisms of Galactic cosmic rays can provide information regarding astrophysical sources, the properties of our Galaxy, and possible exotic sources such as dark matter. To understand cosmic ray acceleration and propagation mechanisms, accurate measurements of different cosmic ray elements over a wide energy range are needed. READ MORE
