Descripción
Neutrinos have been proved to be unique messengers in the understanding of fundamental physics processes, particularly in the astrophysics field. Also, they are thought to be able to provide hints of physics beyond the Standard Model, like Dark Matter models, among which those based on Weakly Interacting Massive Particles (WIMPs) physics. This kind of Dark Matter can scatter off Standard Matter nuclei in the vicinity of massive bodies such as the Sun or the Earth, lose velocity, and be gravitationally trapped in the center of the body. Self-annihilation of dark matter into Standard Model particles results in a flux of which the final products include neutrinos. For the case of the Earth, an excess of neutrinos coming from the center of the planet could indicate that the process described is taking place. The IceCube Neutrino Observatory, located at the geographical South Pole, can detect the neutrino flux described. A search has been conducted on 8 years of IceCube data, probing multiple dark matter channels and masses. The latest sensitivities of this analysis are competitive, world-leading in a part of the phase space, in comparison with previous analyses performed in the field.
