Geoneutrinos: a new tool to study the Earth Livia LudhovaOur planet continues to keep many secrets, even if we live directly on its surface. Fundamental questions concerning, for example, the Earth’s formation, chemical composition, dynamics or heat sources remain unanswered. In particular, we lack information about the deep Earth, from where it is impossible to obtain samples directly. It took more than four decades from the first ideas to exploit (anti)neutrinos from the decays of long-lived radioactive elements inside the Earth to trace their abundances and distributions, until the first actual measurements. Until now, only the KamLAND and the Borexino experiments succeeded to prove that the measurement of geoneutrinos, as we call these neutrinos today, is feasible. Furthermore, these results have proven, that the measured geoneutrino signals are well compatible with the expectations coming from the geological models. Current experimental results, still limited in statistics of detected geoneutrinos, start to hint the first geologically significant results. However, to fully exploit the potential of this new experimental technique, new generation of large volume detectors, potentially placed in geologically suitable locations, has to be built. Today, neutrino geoscience is a newly born interdisciplinary field having as its main aim determination of the Earth’s radiogenic heat, a key parameter in understanding of our planet. The talk will summarize its potential in terms of geosciences, underline experimental difficulties, as well as provide an overview of existing results and perspectives of future prospects. |
