Description
Large-volume neutrino telescopes designed for TeV neutrino astronomy can probe the Earth’s interior through the absorption of atmospheric neutrinos traversing the planet. This provides an independent constraint on the Earth’s radial density profile, complementing conventional methods based on seismic velocity measurements. The next-generation TRopIcal DEep-sea Neutrino Telescope (TRIDENT), located in the South China Sea, is expected to offer strong sensitivity to the Earth's internal density structure. In this work, we present a study of TRIDENT’s Earth tomography sensitivity by simulating atmospheric neutrinos in the 1–100 TeV range. We reconstruct the posterior distributions of a multi-layer radial density model and investigate the impact of different geophysical constraints.We also evaluate the impact of major systematic uncertainties and study TRIDENT’s sensitivity to localized density anomalies.
