Description
While seismology remains the primary tool for studying Earth's internal structure, neutrinos offer two complementary and independent approaches to probe our planet's composition. At energies above TeV, the increasing neutrino interaction cross section enables Earth tomography through flux attenuation measurements—a technique that has already yielded experimental results. Conversely, atmospheric neutrinos around GeV energies undergo flavor oscillations that are modified by matter effects as they traverse the Earth, making them sensitive probes of the planet's interior. Although this lower-energy approach holds significant promise, it has remained experimentally inaccessible due to detector limitations that will be overcome by next-generation neutrino detectors currently under construction. This talk will examine how these upcoming facilities, combined with existing high-energy neutrino telescopes, will enhance our ability to study Earth's internal structure with neutrinos.
