Abstract
Dark matter from the Galactic dark matter halo could scatter off of nuclei in the Sun and become gravitationally captured, accumulating in the center. The accumulated dark matter may annihilate into standard model particles and produce energetic neutrinos in sequent decays. Neutrinos with energies below a few hundred GeV escape the Sun without any significant absorption and can be searched for using a neutrino telescope. IceCube has produced the most stringent bounds on spin-dependent scattering of dark matter with hydrogen by looking for this signal. We present IceCube’s latest solar dark matter search results including a new all-neutrino flavor result that substantially improves IceCube’s sensitivity for dark matter particles with masses below O(100) GeV.
