论文摘要
在受约束的顺序优势（CSD）中，已经解释了中微子部门中的三个束缚混合（TBM）模式，通过提出模型的右手中微子的一定Yukawa耦合结构。但是，从当前的实验数据中可以知道，中微子混合角的值与TBM值偏离。为了解释这种中微子混合，我们首先提出了一个现象学模型，我们认为Yukawa耦合是根据CSD修改的。从本质上讲，我们在CSD的Yukawa耦合中添加了小的复杂参数。使用这些修改的Yukawa耦合，我们证明了中微子混合角可以偏离其TBM值。我们还基于风味对称性构建了一个模型，以证明我们作品的Yukawa耦合的修改形式是合理的。
In the constrained sequential dominance (CSD), tri-bimaximal mixing (TBM) pattern in the neutrino sector has been explained, by proposing a certain Yukawa coupling structure for the right-handed neutrinos of the model. However, from the current experimental data it is known that the values of neutrino mixing angles are deviated from the TBM values. In order to explain this neutrino mixing, we first propose a phenomenological model where we consider Yukawa couplings which are modified from that of CSD. Essentially, we add small complex parameters to the Yukawa couplings of CSD. Using these modified Yukawa couplings, we demonstrate that neutrino mixing angles can deviate from their TBM values. We also construct a model, based on a flavor symmetry, in order to justify the modified form of Yukawa couplings of our work.
