Indirect dark matter searches at ultrahigh energy neutrino detectors
Original language description
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
