[SCG42-01] Study of the Earth’s interior with high energy neutrinos

Keywords:Neutrino Oscillation Spectrography, Neutrino Absorption Tomography, Neutrino Telescopes, IceCube, Neutrinos

Neutrinos produced naturally in the atmosphere or at astrophysical sources traverse the Earth and can provide clues about our home planet's interior structure and composition.
Matter induced neutrino oscillations depend on the Earth's electron density, while seismic measurements are sensitive to the matter density. This difference provides sensitivity to test the Earth's chemical composition by combining observations from large neutrino detectors with seismic measurements. Further highest energy neutrinos get absorbed in the Earth with a probability that depends on the mass density along their path providing sensitivity to measurements of the density profile. The presentation will introduce current measurements conducted with IceCube Neutrino Telescope and discuss the science potential of the next generation of large volume neutrino detectors and telescopes including Hyper-K, KM3NeT, IceCube-Gen2.
