KamLAND: geo-neutrino measurement in Japan

Itaru Shimizu


Geoneutrinos are antineutrinos produced in radioactive isotope decays inside the Earth. Those antineutrinos are neutral particle and can be detected by weak interaction, however, due to extremely small cross section, there were no feasible experiments for a long time. The observation of geoneutrinos has been finally made using large-size liquid scintillator detectors, KamLAND and Borexino. In this article, the latest result of KamLAND and future prospects of geo νe measurements are reviewed.
