Decaying dark matter at IceCube and its signature on High Energy gamma experiments

Understand

The origin of neutrino flux observed in IceCube is still mainly unknown.

• Typically two flux components are assumed, namely: atmospheric neutrinos and an unknown astrophysical term.
• In principle the latter could also contain a top-down contribution coming for example from decaying dark matter.
• In this case one should also expect prompt and secondary gammas as well.
