New measurements of the geo-neutrino flux are available from two independent and complementary experiments: Borexino and KamLAND. These new data decrease uncertainties on the flux and the derived radiogenic contribution to the terrestrial heat flow begins to be significant. The derived heat flow has a theoretical uncertainty from the accepted model of Earth. In the new future the range of the predictions should decrease mainly because of larger statistics collected by the two experiments and the new data from SNO+ should contribute to discriminate among different models of heat production in the Earth.

Abstract
New measurements of the geo-neutrino flux are available from two independent and complementary experiments: Borexino and KamLAND. These new data decrease uncertainties on the flux and the derived radiogenic contribution to the terrestrial heat flow begins to be significant. The derived heat flow has a theoretical uncertainty from the accepted model of Earth. In the new future the range of the predictions should decrease mainly because of larger statistics collected by the two experiments and the new data from SNO+ should contribute to discriminate among different models of heat production in the Earth.File in questo prodotto:
