论文摘要
我们更新并改善了过去的努力，以预测Leptonic Dirac CP侵略阶段，这些模型可以预测扰动修改的Trimaximal或Bimaximal混合。简单的扰动应用于两个部门之间旋转形式的两种混合模式。通过将这些扰动的混合矩阵转换为中微子混合矩阵的标准参数化，我们得出了狄拉克CP期与振荡角之间的关系。我们将这些关系与当前的实验结果一起使用，以限制CP期的允许范围并确定其概率密度。此外，我们详细介绍了未来实验的前景，以探测这项工作中考虑的扰动。我们提出了一个具有$ A_4 $模块化对称性的模型，该模型与所描述的扰动方案之一一致，并成功预测了当前的振荡参数数据。
We update and improve past efforts to predict the leptonic Dirac CP-violating phase with models that predict perturbatively modified tribimaximal or bimaximal mixing. Simple perturbations are applied to both mixing patterns in the form of rotations between two sectors. By translating these perturbed mixing matrices to the standard parameterization for the neutrino mixing matrix we derive relations between the Dirac CP-phase and the oscillation angles. We use these relations together with current experimental results to constrain the allowed range for the CP-phase and determine its probability density. Furthermore, we elaborate on the prospects for future experiments probing on the perturbations considered in this work. We present a model with $A_4$ modular symmetry that is consistent with one of the described perturbed scenarios and successfully predicts current oscillation parameter data.
