标题： Probing the Sun's inner core using solar neutrinos: a new diagnostic method

摘要： 太阳内核的电子密度是通过Super-Kamiokande、SNO和Borexino实验对8B、7Be和pep中微子通量的测量推断得出的。 我们开发了一种新方法，其中我们使用KamLAND探测器对中微子基本振荡参数（质量差和真空振荡角）的测定。 我们的结果表明，太阳内核中的太阳电子密度（半径小于太阳半径10%的区域）明显高于标准太阳模型的当前预测，甚至高出25%。 当中微子探测器能够将电子中微子存活概率的误差降低15倍时，可以确认这些初步结果。 显示英文摘要

摘要： The electronic density in the Sun's inner core is inferred from the 8B, 7Be 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.
