Description
Dark matter particles can form halos gravitationally bound to massive astrophysical objects. The Earth could have such a halo where depending on the particle mass, the halo either extends beyond the surface or is confined to the Earth's interior. We consider the possibility that if dark matter particles are coupled to neutrinos, then neutrino oscillations can be used to probe the Earth's dark matter halo. In particular, atmospheric neutrinos traversing through the Earth can be sensitive to a small size, interior halo that is otherwise inaccessible. The constraint on the dark matter-neutrino coupling depends on the halo mass and neutrino energy.
