Geoneutrinos, antineutrinos originating from Earth’s natural radioactivity, offer insights into the definition of the Earth’s heat budget.

Abstract
Geoneutrinos, antineutrinos originating from Earth’s natural radioactivity, offer insights into the definition of the Earth’s heat budget. To date, the KamLAND (Japan) and Borexino (Italy) experiments have both successfully measured the geoneutrino flux. The information was merged to achieve a mantle geoneutrino signal of 8.9+5.1−5.5 TNU and Earth’s radiogenic heat of 20.8+7.3−7.9 TW, consistent with the 19.7±3.1 TW estimated from geochemical Bulk Silicate Models. Future geoneutrino research will involve multi-site mantle analysis, new detectors (SNO+ and JUNO), and advancements in experimental techniques, such as detecting antineutrino directionality and potassium geoneutrinos.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
