Description
Borexino has recently updated the electron antineutrino measurement with 906 ton-year exposure. In the whole dataset 77 antinu candidates have been identified after the application of the selection cuts. Exploiting the selected sample, Borexino alone has been in condition to prove the detection of the geo-neutrino signal with a significance as high as 5.9 sigma.
Moreover, from the same data a geo-neutrino signal from the mantle is inferred at 98% C.L., and the radiogenic heat production for U and Th is restricted to the range 23-36 TW, taking into account the uncertainty on the distribution of heat producing elements inside the Earth. In the talk, such findings will be thoroughly illustrated and discussed.
