Status of indirect dark matter detection
Résumé
Indirect astrophysical channels (such as gamma rays, neutrinos, and cosmic ray antimatter) are a cornerstone in the dark matter particle identification program. A review of the present constraints is presented, together with some perspectives for the near future: we argue that the approach of "fitting any spectral feature to a dark matter model" is unlikely to lead to a convincing indirect detection of dark matter. Rather--if the WIMP paradigm for dark matter is correct--guidance from collider and direct detection programs is expected to allow soon for more fruitful a priori searches of correlated signatures in many indirect channels.
