Abstract

We investigate the status of light Dark Matter DM particles from their residual annihilation and discuss the range of the DM mass and total annihilation cross section compatible with gamma-rays experiment data. We find that particles as light as a few MeV or up to ~ 10 GeV could represent an interesting alternative to the standard picture of very massive WIMPs.
