太阳中微子物理振荡:对太阳核心电子密度的敏感性

Solar neutrino physics oscillations: Sensitivity to the electronic density in the Sun's core

Ilídio Lopes, Sylvaine Turck-Chièze

摘要:

来自不同核反应的太阳中微子现在被探测到具有很高的统计。因此,在中微子振荡的背景下,可以对到达地球探测器的中微子通量进行精确的光谱分析。在这项工作中,我们探讨了使用这些信息来推断太阳核心中电子密度的径向分布的可能性。因此,我们讨论了可以通过太阳中微子观测确定的太阳密度和化学成分的限制。这种方法构成了对已经完成的日震调查的独立和替代诊断。本文提出的直接反演太阳径向电子密度分布的方法,几乎不依赖于太阳模型。

英文摘要:

Solar neutrinos coming from different nuclear reactions are now detected with a high statistics. Consequently, an accurate spectroscopic analysis of the neutrino fluxes arriving on the Earth's detectors become available, in the context of neutrino oscillations. In this work, we explore the possibility of using this information to infer the radial profile of the electronic density in the solar core. So, we discuss the constraints on the Sun's density and chemical composition that can be determined from solar neutrino observations. This approach constitutes an independent and alternative diagnostic to the helioseismic investigations already done. The direct inversion method, that we propose to get the radial solar electronic density profile, is almost independent of the solar model.
