Description
Positrons in cosmic rays have been measured by the Pamela satellite and more recently by the Fermi-LAT instrument. Their ratio to electrons increases with energy, indicating the presence of a primary source in the Galaxy. We investigate the possibility that their source resides in Dark Matter particles and discuss the possible astrophysical sources and backgrounds.
