Dark matter particles in the galactic halo can scatter off particles in
celestial bodies such as stars or planets, lose energy and become
gravitationally trapped. In this process, an accumulation of dark matter in the
center of celestial bodies is expected, for example, at the center of the
Earth. If dark matter self-annihilates into Standard Model particles, the end
products of these annihilations include neutrinos. The IceCube Neutrino
Observatory at the geographic South Pole can detect the resulting flux of
neutrinos originating from dark matter annihilation in the center of the Earth.
A search for this signal is on-going using 8 years of IceCube data and probing
different annihilation channels. Here the sensitivities are presented for this
new analysis, showing significant improvements with respect to the previous
analyses from IceCube and other experiments.
