Solar Neutrino Flux Variability

Sturrock，Peter”Solar Neutrino Flux Variability“AST-0097128近年来，太阳中微子观测的不足一直是太阳天体物理学中最有趣的问题之一。 大多数研究人员现在认为，这更多的是中微子物理学的结果，并解释了电子中微子在飞出太阳中心时转化为μ子或τ中微子的结果。由于太阳的结构非常稳定，中微子的流量应该是恒定的。但是在这个奖项中提到的论点中，PI和他的合作者认为磁场可能发挥了重要作用。在最近的论文中，他们指出，如果中微子的磁矩非常小，那么太阳的磁场，不是各向同性分布的，可以通过将左手中微子转换为右手中微子来调制中子通量，而右手中微子不会被地面探测器记录。PI和他的团队支持他们的理论，声称来自太阳的中微子通量随着接近深对流区旋转周期的周期而变化。证据来自对现有Homestake和GALLEX-GNO数据的复杂分析。有许多人批评这种分析。该奖项的主要工作将是通过审查以前的分析来解决批评，并为研究超级神冈数据和其他数据集做好准备。

Sturrock, Peter" Solar Neutrino Flux Variability "AST- 0097128The deficiency of observed neutrinos emanating from the Sun has been one of the most intriguing problems of solar astrophysics in recent years. Most researchers now believe that this is more a consequence of neutrino physics and explain the deficiency as a consequence of the transformation of electron neutrinos into muon or tau neutrinos as they fly out of the center of the Sun. Since the Sun's structure is very stable, the flux of neutrinos should be constant. But in arguments that are addressed in this award, the PI and his collaborators believe that magnetic fields may play an important part. In recent papers, they point out that, if the neutrino has a very small magnetic moment, then the magnetic field of the sun, which is not distributed isotropically, could modulate the neutron flux by converting left-handed neutrinos into right-handed neutrinos which would not be registered by terrestrial detectors. The PI and his team support their theory by claiming that the neutrino flux from the Sun varies with a period close to the rotation period of the deep convection zone. The evidence comes from a sophisticated analysis of existing Homestake and GALLEX-GNO data. There are many critics of this analysis. The principal effort made in this award will be to address the critics by reviewing previous analyses and to make preparations for the study of the Super-Kamiokande data and other data sets, as they become available.***
