Improved methods for solar Dark Matter searches with the IceCube neutrino telescope
Gravitationally captured Dark Matter in the form of Weakly Interacting Massive Particles(WIMPs) can annihilate into standard-model particles, such as neutrinos. The IceCube neutrinodetector at the South Pole is an excellent instrument to search for such a neutrino signal fromthe Sun. We present an a...
