摘要:

首先,我们调查的可能性检测太阳反中微子的KamLAND实验。然后,我们分析了第一个Borexino数据发布约束中微子磁矩。最后,我们研究了太阳中微子的共振自旋味转换为不育的,这是一个机制,这是众所周知的LMA之一。在这最后一个条件下,我们表明,从所有的太阳中微子实验的数据,除了Borexino表现出一个相当大的磁场明显的偏好。我们认为,太阳中微子实验是能够跟踪太阳磁场的可能调制。这样,Borexino单独可能发挥重要作用,尽管来自其他实验的实验冗余将是最重要的。

英文摘要:

First we investigate the possibility of detecting solar antineutrinos with the KamLAND experiment. Then we analyze the first Borexino data release to constrain the neutrino magnetic moment. Finally we investigate the resonant spin flavour conversion of solar neutrinos to sterile ones, a mechanism which is added to the well known LMA one. In this last condition, we show that the data from all solar neutrino experiments except Borexino exhibit a clear preference for a sizable magnetic field. We argue that the solar neutrino experiments are capable of tracing the possible modulation of the solar magnetic field. In this way Borexino alone may play an essential role although experimental redundancy from other experiments will be most important.
