100 years of cosmic rays: present and future of cosmic-ray propagation models
Oskar Klein Centre Stockholm
One century after the discovery of cosmic rays by V. Hess, many questions still remain open on their origin, nature, and transport. In particular, the knowledge and the characterisation of the processes related to the propagation make it possible to reconstruct the cosmic-ray source spectrum and thus to constrain the acceleration processes, but also to test the existence of exotic contributions such as the annihilation of dark-matter particles. In this talk I will give an overview of the most commonly used propagation models and will confront them with recent cosmic-ray data from experiments, such as PAMELA. An outlook for future model refinements will also be given.
