ملخص المقال

The Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics (PAMELA)
has now provided a very accurate measurement of the spectrum of cosmic-ray electrons and
positrons. These results are consistent with a single power-law, but visually they suggest an
excess emission from about 100 GeV to 1 TeV, which leads to the emergence of a debate about
the existence and the source of this excess: Could come from nearby pulsars or dark-matter
annihilation? We do not know, each one has its reasons. In this work we will try to study
this controversy by clarifying this spectrum using the GALPROP code.
