Description
Neutrinos are helpful messenger particles to indirectly search for the decay or annihilation of dark matter particle and constrain a variety of dark matter models. The IceCube neutrino telescope measures Cherenkov light from charged particles created by the interaction of neutrinos in a cubic kilometer of Antarctic ice. Already during its construction period, IceCube has taken data that was put through a variety of analyses with focus on WIMPs in the Galactic halo, the Galactic center, dwarf galaxies and the sun. With the increasing number of deployed strings, the sensitivity especially towards lower WIMP masses gradually improved and finally put new competitive limits on the spin-dependent proton scattering cross section. The planned low-energy extension PINGU would provide improved sensitivity to dark matter and after 1 year live-time cut into possible signal regions from DAMA/LIBRA and CoGeNT.
