Neutrino Oscillation Tomography - or - What Could One Learn About the Earth's Interior from Neutrino Oscillations in Matter?

Earth matter effects are often being taken into account in the calculation of long baseline energy spectra, since neutrino oscillations can be quite substantially influenced by matter. One interesting application is the inverse problem: Assume that we know the neutrino mixing angles and mass squared differences quite well, what can we learn about the Earth matter density profile from a single baseline energy spectrum? We will especially apply this idea to two problems: The reconstruction of the Earth's matter density profile and the search for large cavities in the Earth's mantle.

Based on T.Ohlsson & W.Winter, "Reconstruction of the Earth's matter density profile using a single neutrino baseline", Phys. Lett. B 512 (2001) 357 [hep-ph/0105293] and "Could One Find Petroleum Using Neutrino Oscillations in Matter?" hep-ph/0111247
