NSI可以改进LMA的预测:太阳物质中的中微子衰变?

NSI can improve LMA predictions: neutrino decay in solar matter?

Joao Pulido, C. R. Das

摘要:

我们研究了太阳中微子传播和探测中的非标准相互作用(NSI)的前景,发现这些可能会解决观测到的SuperKamiokande电子谱的平坦性与其LMA预测之间的紧张关系,该预测具有明显的负斜率。此外,NSI的Cl率预测值在其实验值的1 $σ$范围内,而不是LMA值,后者高于2 $σ$。NSI对太阳中微子的一个显著的结果是中微子衰变为强子和反中微子的可能性,计算了它们的出现概率,但发现它们的出现概率相当小。

英文摘要:

We investigate the prospects for non-standard interactions (NSI) in solar neutrino propagation and detection and find that these may solve the tension between the observed flatness of the SuperKamiokande electron spectrum and its LMA prediction which has a clear negative slope. Also the Cl rate prediction from NSI comes within 1$σ$ of its experimental value instead of the LMA one which lies more than 2$σ$ above. A remarkable consequence of NSI for solar neutrinos is the possibility of neutrino decay into majorons and antineutrinos whose appearance probability is calculated but found to be rather small.
