Detection of Geoneutrinos by KamLAND Detector

Yuri Efremenko, University of Tennessee
Building 6008 Conference Room

It is a well-established fact that the decay of long-lived isotopes is a powerful source of heat generated inside the Earth. Antineutrinos produced during the decay of those isotopes can escape from the interior of our planet and be detected. First results of the detection of geoneutrinos using the one-kiloton liquid scintillator KamLAND detector located deep in a mine in central Japan were published last week. This opens a new window to study the Earth's interior.
