Search for dark matter from the Galactic halo with the IceCube Neutrino Telescope

Abstract: Self-annihilating or decaying dark matter in the Galactic halo might produce high energy neutrinos detectable with neutrino telescopes. We have conducted a search for such a signal using 276 days of data from the IceCube 22-string configuration detector acquired during 2007 and 2008. The effect of halo model choice in the extracted limit is reduced by performing a search that considers the outer halo region and not the Galactic Center. We constrain any large scale neutrino anisotropy and are able to set a limi… Show more

“…J → W W, ZZ that could be induced in some UV-completions of our model. We stress, however, that J → νν could still be an important discovery channel for majoron masses up to 10 TeV, for which IceCube becomes the ideal observatory [63,64]. The neutrino (plus antineutrino) flux per flavor from the J → νν decay in our galaxy is given by [26,65] …”

“…Also, in this context, some have considered the isotropic arrival directions of cosmic neutrinos to be a clue that they originate in the Galactic halo as a result of the decay of PeV-energy dark matter particles, a speculation that at this point is perfectly consistent with observations [33][34][35][36][37][38][39][40] . More traditionally, IceCube searches for dark matter by looking for the annihilation of weakly interacting massive particles (WIMPs) wherever they have accumulated to a high density: in the Sun 41 , in the Milky Way 42,43 , and in nearby galaxies 44 . For instance, WIMPs are swept up by the Sun as the solar system moves about the galactic halo.…”

“…Ice Cube has now reported limits on the annihilation cross section into several channels through observations of the diffuse Galactic halo with an exposure of 276 days and a 22-string configuration (Abbasi et al, 2011). For dark matter mass greater than 20 GeV, the best-constrained channel is the direct annihilation of dark matter to neutrinos, for which the limits are σ ann v 10 −22 cm 3 s −1 .…”
