Description
The Jiangmen Underground Neutrino Observatory (JUNO) is a 20-kton liquid scintillator experiment located 650 meters underground in China. Its primary scientific goal is to determine the neutrino mass ordering through high-precision measurements of reactor neutrinos at a 52.5 km baseline. Beyond its core mission, JUNO’s large target volume and excellent detection performance make it a powerful detector for geoneutrinos. Geoneutrinos are produced by the decays of long-lived radioactive isotopes in the Earth’s interior, including uranium, thorium, and potassium. Due to the inverse beta decay threshold, JUNO is exclusively sensitive to geoneutrinos from the decay chains of 238U and 232Th. The geoneutrino flux is directly proportional to the abundances of U and Th, whose decays generate a major fraction of the Earth’s radiogenic heat, offering unique and direct constraints on the terrestrial energy budget and interior structure. This talk will present the geoneutrino analysis at JUNO using the latest data. JUNO’s capability to detect and analyze geoneutrino signals will be discussed, laying the foundation for future high-precision studies in both neutrino physics and geoscience.
