Geo-neutrino: experimental status and perspectives

Oleg Smirnov (JINR, Dubna, Russia)




Last year KamLAND collaboration presented preliminary analysis of the data taken after the shutdown of nuclear power plants. 

In the absence of the background from nuclear reactors the geo-neutrino signal dominates in the observed spectrum, precision
of geoneutrino signal measurement approaches 15%. Together with Borexino measurements the new KamLAND data offers
an opportunity for the discrimination of the geophysical models of the Earth. The separation of the geo-neutrino signal from mantle is of special interest for geophysicists.

The current results of the Borexino and KamLAND will be presented. The perspectives for measurement of geo-neutrino fluxes both
on existing and planned detectors (SNO+, JUNO) will be discussed. We will discuss also the nuclear physics inputs relevant for high precision measurement of the geo-neutrino fluxes in the future.
