Galactic Cosmic Rays (GCRs)
- Vincent Tatischeff (CSNSM)
The session is dedicated to a review of GCR studies (experiments and phenomenology). We start with a general review of their importance to study standard astrophysical mechanisms (and also to study dark matter indirect searches). Focusing on the nuclear component, the issue of fragmentation is emphasised: the limitation on CR phenomenology studies brought by the cross sections uncertainties are detailed. The impact of these cross sections is also discussed in the light of the CR flux reconstruction from various contemporary experiments (the balloon-borne CREAM, the PAMELA satellite, AMS-01 on the shuttle and AMS-02 on the ISS).
