Probing dark matter dynamics via earthborn neutrinos at IceCube

Abstract

Recent results from PAMELA and ATIC hint that (TeV) dark matter (DM) is annihilating, in our galactic neighborhood, mainly to leptons. The present annihilation rate is larger than at freeze-out, possibly due to a low-velocity enhancement. In this case the rate of neutrino emission from the Earth, due to DM annihilation, may be greatly enhanced while the rate from the Sun is unaltered. Neutrino telescopes may see these earthborn neutrinos. Combining with the data from direct detection experiments will yield valuable information about the DM sector. © SISSA 2009.
