Abstract
The Borexino detector can detect antineutrino fluxes as well as solar neutrinos fluxes using neutrinoelectron scattering reaction. Antineutrino fluxes are produced inside the Earth by isotopes of natural radioactivity and on the Earth’s surface by reactor cores of nuclear power plants. We analyzed the latest data from the Borexino detector adding to the analysis of solar neutrino fluxes the antineutrino ones, adding them to the known backgrounds. The result of the analysis was that non-zero antineutrino flux from 40K was found. At the same time, all solar neutrino fluxes began to be consistent with the low metallicity Sun model.
