Description

Several models predict that dark matter is constituted of Weakly Interacting Massive Particles (WIMPs). These hypothetical particles would be attracted by the gravity of massive astronomical objects such as black holes, stars, and the Earth. WIMPs can loose energy through scattering with matter and become trapped in the gravitational field of mentioned massive objects. Finally, WIMPs would annihilate via mutual interactions or decay resulting in production of Standard Model particles. If neutrinos are created, they will escape, as they pass through the ordinary matter almost unaffected, and create a neutrino flux. This contribution describes the search for WIMPs accumulated in the center of the Earth using the IceCube neutrino observatory located at the geographic South Pole. Results from the analysis with one year of IceCube data from 2011 will be presented along with the sensitivity for several additional years of data.
