Abstract
We consider dark matter consisting of long--living particles with masses GeV decaying through hadronic channel as a source of high energy neutrino. Using recent data on high energy neutrino from IceCube and Pierre Auger experiments we derive the upper-limits on neutrino flux from dark matter decay and constraints on dark matter parameter space. For the dark matter masses of order GeV the constraints derived are slightly stronger than those obtained for the same dark matter model using the high energy gamma-ray limits.
