Title: Probing the Sun's inner core using solar neutrinos: A new diagnostic method
Authors: Lopes, Ilidio
Keywords: Sun
Issue Date: 7-Aug-2013
Abstract: The electronic density in the Sun’s inner core is inferred from the B8, Be7 and pep neutrino flux measurements of the Super-Kamiokande, SNO and Borexino experiments. We have developed a new method in which we use the KamLAND detector determinations of the neutrino fundamental oscillation parameters: the mass difference and the vacuum oscillation angle. Our results suggest that the solar electronic density in the Sun’s inner core (for a radius smaller than 10% of the solar radius) is well above the current prediction of the standard solar model, and by as much as 25%. A potential confirmation of these preliminary findings can be achieved when neutrino detectors are able to reduce the error of the electron-neutrino survival probability by a factor of 15.
