Talk Dark Matter Indirect Searches Plenary session : Indirect Searches 1

Description

Some of the antimatter (antiprotons or positrons) present in cosmic rays could be due to the annihilation of dark matter particles. Indirect searches based on these signals require to be able to model the propagation process, from the annihilation location to the Solar System. The physical processes are well known : diffusion, convection, energy losses and reacceleration. The physical parameters describing these effect (diffusion coefficient, convection velocity, etc) can be constrained by studying secondary-to-primary ratios of nuclei in cosmic rays. I will present the uncertainties related to this procedure and the importance for indirect searches or dark matter.
