Abstract
Ultra-high-energy (UHE) neutrino and gamma-ray measurements will help on the dark matter (DM) quest via indirect detection. In this work we used UHE measurements of the astrophysical gamma-ray flux and we forecasted the performance of the future radio neutrino telescopes in order to see the potential limits that they could place on the lifetime of DM particles. We focused in the range of DM masses m DM = [107 — 1015] GeV. We provide the current gamma-ray limits placed by the different experimental collaborations CASA-MIA, KASCADE KASCADE-Grande, Pierre Auger Observatory, Telescope Array and EAS-MSU. We also compare this limits with the projected UHE neutrino ones from future radio neutrino telescopes in order to see the complementarity between both messengers. For a more detailed description of the analysis we refer the reader to [1, 2, 3].
