| « Constraining Dark Matter with cosmic ray data » |
|
T. Delahaye |
| Recent PAMELA data seem to indicate an excess in positron cosmic rays around ~10 GeV that may be due to galactic Dark Matter particle annihilation. I will explain how the background of this signal is estimated and focus on the uncertainties that make our task difficult in constraining Dark Matter. I will explain how analysing simultaneously different cosmic ray particles is the only way to have an insight in the nature of Dark Matter. Finally I will briefly present what is required to perform better analysis. |
