论文摘要
我们审查并研究了由一个或两个自由模型参数描述的离散的非亚伯风味对称性的Lepton风味模型。首先，我们面对11个和7个两参数模型，目前在整体中微子振荡数据的麻细胞混合角度上进行了当前的结果。我们发现，两参数模型中的五个和五个模型中的五个在对抗测试中以$3σ$幸存。其次，我们研究了这十个一参数和两参数Lepton风味模型如何在瑞典的Essnusb实验中被区分。我们表明，可以将预测$ \sinδ_ {\ rm cp} = 0 $的三个单参数模型与预测$ | \sinδ_ {\ rm cp} | = 1 $至少至少$7σ$的两个区分。最后，我们发现，如果五个单参数型号中的三个至少5σ$，其中两个单参数以及两个两参数模型中的最多都可以排除在五个五个参数模型中，则至少可以将至少$3σ$与Essnusb一起排除，如果Leptonic混合参数的真实值保持在接近当前的最佳效果值。
We review and investigate lepton flavor models, stemming from discrete non-Abelian flavor symmetries, described by one or two free model parameters. First, we confront eleven one- and seven two-parameter models with current results on leptonic mixing angles from global fits to neutrino oscillation data. We find that five of the one- and five of the two-parameter models survive the confrontation test at $3σ$. Second, we investigate how these ten one- and two-parameter lepton flavor models may be discriminated at the proposed ESSnuSB experiment in Sweden. We show that the three one-parameter models that predict $\sinδ_{\rm CP}=0$ can be distinguished from those two that predict $|\sinδ_{\rm CP}|=1$ by at least $7σ$. Finally, we find that three of the five one-parameter models can be excluded by at least $5σ$ and two of the one-parameter as well as at most two of the five two-parameter models can be excluded by at least $3σ$ with ESSnuSB if the true values of the leptonic mixing parameters remain close to the present best-fit values.
