| « Implications of the Cosmic Ray Anomalies on Dark Matter » |
|
Pierre Salati |
| One of the favorite candidates to the astronomical dark matter is a massive and weakly interacting particle. Such a species arises naturally in the framework of supersymmetry or in extensions of the standard model à la Kaluza-Klein. Should they pervade the halo of the Milky Way, these dark matter particles would annihilate with each other and produce positrons and antiprotons. A positron excess has actually been reported by the PAMELA collaboration above 10 GeV whereas the antiproton flux seems compatible with conventional astrophysical processes. I will present these observations together with their current explanations and analyze the consequences on the properties of the putative dark matter particles. |
