论文摘要
Lepton混合矩阵的$μ-τ$反射对称性可容纳最大大气混合（$θ_{23} =π/4 $）以及最大的Dirac CP相位（$Δ= \pmπ/2 $）。在PMNS矩阵的标准参数化中，反射对称性质在代替混合参数的最大值时不直接可见。本文已经解决了这个问题。发现“标准” PMNS矩阵中的反射对称性也可以通过允许Majorana CP阶段的最大值（$α$，$β$）以及最大$Δ$来恢复。为了适应$θ_{23} $和$δ$的非最大值值，我们考虑了对中微子混合的充电Lepton贡献，并在中微子混合矩阵中实现了建议的反射对称方案。充电的Lepton校正方案在Lepton混合参数的预测与全局$3ν$振荡数据一致的预测中取得了成功。
The $μ-τ$ reflection symmetry of the lepton mixing matrix accommodates maximal atmospheric mixing ($θ_{23}=π/4$) as well as maximal Dirac CP phase ($δ=\pm π/2$) for the Dirac case. In the standard parametrization of the PMNS matrix the reflection symmetric nature is not directly visible while substituting the maximal values of the mixing parameters. This issue has been addressed in this paper. It is found that the reflection symmetry in the 'standard' PMNS matrix can be restored by allowing maximal values of the Majorana CP phases ($α$, $β$) as well, along with maximal $δ$. To accommodate non-maximal values of $θ_{23}$ and $δ$ we consider charged lepton contributions to the neutrino mixing and implement the proposed scheme of reflection symmetry in the neutrino mixing matrix. The charged lepton correction scheme succeeds in the prediction of lepton mixing parameters consistent with the global $3ν$ oscillation data.
