The first results from the Borexino experiment show for the first time, in real time, the spectrum of the low energy neutrinos from the Sun.
The Borexino experiment, which started the data taking in May 2007, measured the spectrum of neutrinos with energy greater than a few hundreds keV clear showing the signal of the neutrinos produced in the beryllium reaction chains. The first results are consistent with the prediction of the Solar Standard Model and with the current theories on the neutrino oscillations.
The researchers involved in Borexino won an extreme technological challenge enabling the analysis of a large fraction of the solar neutrino spectrum which had not been explored in real time experiments so far; until now only the high energy neutrinos representing less than 0.01 percent of all the neutrinos produced by our star.
