Description
The study of geoneutrinos produced from radioactive beta decay in the Earth's crust and mantle offers insight into the planet's heat budget, with these decays from primordial isotopes providing a significant but incompletely understood contribution to Earth's internal heat. After their initial detection a few years back, upcoming large-scale experiments are anticipated to detect geoneutrinos in larger quantities, with the spectral flux measurements promising to refine our understanding of isotopic ratios within Earth's interior. Accurately predicting the geoneutrino spectral shape, however, requires a deep understanding of beta decay processes, which include quantum field theoretical corrections and nuclear structure effects. Currently, substantial approximations in these areas introduce considerable uncertainty in determining ratios like uranium to thorium within the Earth. By applying methods honed for precise spectroscopy in searches beyond the Standard Model, we aim to refine spectral predictions, enhancing our understanding of how these isotopic ratios impact Earth's formation and contribute to its heat budget.
