Abstract
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 <sigma v > 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. We compare the sensitivities of next generation neutrino experiments with existing constraints from IceCube and updated 90% C.L. upper limits on <sigma v > and Gamma(chi ->nu(nu) over bar) using results from the Pierre Auger Collaboration and Antarctic Impulsive Transient Antenna. We show that in the range 10(7) <= m(V)/GeV <= 10(11), POEMMA and GRAND10k will improve the neutrino sensitivity to particle dark matter by factors of 2 to 10 over existing limits, whereas GRAND200k will improve this sensitivity by 2 orders of magnitude. In the range 10(11) <= m(chi)/GeV <= 10(15), POEMMA's fluorescence observation mode will achieve an unprecedented sensitivity to dark matter properties. Finally, we highlight the importance of the uncertainties related to the dark matter distribution in the galactic halo, using the latest fit and estimates of the galactic parameters.
