Description
I shall discuss a scenario which can explain the shape and flavor content
of very high en ergy neutrinos observed recently by IceCube collaboration.
It works as follows: dark matter decay produces very high energy
sterile neutrinos, with energies order PeV, which then oscillate into active
neutrinos with proper oscillation probabilities, producing VHE neutrinos
with specific spectrum.
