中微子振荡数据的贝叶斯整体分析

Bayesian global analysis of neutrino oscillation data

Johannes Bergstrom, M. C. Gonzalez-Garcia, Michele Maltoni, Thomas Schwetz

摘要:

我们对当前的中微子振荡数据进行了贝叶斯分析。当估计振荡参数时,我们发现结果与$χ^2$方法的结果基本一致,但在涉及$s_{23}^2$和CP破坏效应时存在一些差异。我们讨论了CP破坏阶段的循环性质所引起的额外的微妙之处,以及如何可能获得与$s_{23}^2$的相关系数。当进行模型比较时,我们发现没有任何重大证据表明任何质量排序、$s_{23}^2$的任何八分圆或与最大混合的偏差,也不存在CP违规。

英文摘要:

We perform a Bayesian analysis of current neutrino oscillation data. When estimating the oscillation parameters we find that the results generally agree with those of the $χ^2$ method, with some differences involving $s_{23}^2$ and CP-violating effects. We discuss the additional subtleties caused by the circular nature of the CP-violating phase, and how it is possible to obtain correlation coefficients with $s_{23}^2$. When performing model comparison, we find that there is no significant evidence for any mass ordering, any octant of $s_{23}^2$ or a deviation from maximal mixing, nor the presence of CP-violation.
