Indirect dark matter searches at ultrahigh energy neutrino detectors

Popis výsledku v původním jazyce

High to ultrahigh energy neutrino detectors can uniquely probe the properties of dark matter chi by searching for the secondary neutrinos produced through annihilation and/or decay processes. We evaluate the sensitivities to dark matter thermally averaged annihilation cross section and partial decay width Gamma(chi ->nu(nu) over bar) (in the mass scale 10(7) <= m(chi)/GeV <= 10(15)) for next generation observatories like POEMMA (Probe of Extreme Multi-Messenger Astrophysics) and GRAND (Giant Radio Array for Neutrino Detection). We show that in the range 10(7) <= m(chi)/GeV <= 10(11), space-based Cherenkov detectors like POEMMA have the advantage of full-sky coverage and rapid stewing, enabling an optimized dark matter observation strategy focusing on the Galactic Center. We also show that ground-based radio detectors such as GRAND can achieve high sensitivities and high duty cycles in radio quiet areas.nn
