Description
Dark matter particles which decay into charged fermions produce, via radiative
corrections, monoenergetic gamma rays with a branching ratio that depends on the
details of the dark matter model. We analyze in this talk the prospects to detect
monoenergetic gamma-rays from radiative dark matter decays at present and future
experiments. We also discuss the implications for concrete models of decaying dark
matter, concretely those which can explain the electron/positron excesses observed by
PAMELA and the Fermi-LAT.
