90% c.l. lower limit on dark matter lifetimes for all studied decay channels and masses. An Einasto halo profile following [0] is assumed. The ~13PeV peak is due to the Glashow resonance. The fluctuations at low masses are due to the bin edge effects.
Comparison of the dark matter lifetime limits for a benchmark channel (χ->μμ) between different experiments; previous IceCube analysis [20], HAWC Galactic Centre analysis [21], HAWC M31 analysis [22], FermiLAT [23] and VERITAS [24]. An Einasto halo profile following [19] is assumed.
The colour map shows the expected neutrino signal events in each analysis bin for a dark matter decay model with: χ->μμ, m=1PeV, τ=10^28s. The white '+' and 'x' marks show the best fit directions of HESE (double) cascade and track events respectively. HESE events below 60TeV are not shown as they are not considered in this analysis. An Einasto halo profile following [0] is assumed.
Simulated neutrino spectra in the dark matter rest-frame for all investigated annihilation/decay channels. Emax denotes the dark matter mass/half the dark matter mass for annihilation/decay respectively. At the high masses considered here, the shape of the spectra is, up to a scaling factor, identical for all masses.
