超对称额外U(1)模型中的中微子质量和$μ$项

Neutrino masses and $μ$ terms in a supersymmetric extra U(1) model

Daijiro Suematsu, Takashi Toma, Tetsuro Yoshida

摘要:

我们提出了一个超对称额外U(1)模型,它能同时产生小质量的中微子和必要的$μ$项.包括夸克和轻子在内的场以不同的方式嵌入$E_6$的三个${\bf 27}$中。该模型在TeV区具有额外的U(1)规范对称性,这与以往研究的其他模型有区别。由于模型中引入的中微子质量矩阵具有有限参数的约束结构,因此可以给出预测。如果我们利用中微子振荡数据来固定这些参数,就可以确定$\sinθ_{13}$的值。我们还讨论了几个唯象的功能,区别于MSSM的。

英文摘要:

We propose a supersymmetric extra U(1) model, which can generate small neutrino masses and necessary $μ$ terms, simultaneously. Fields including quarks and leptons are embedded in three ${\bf 27}$s of $E_6$ in a different way among generations. The model has an extra U(1) gauge symmetry at TeV regions, which has discriminating features from other models studied previously. Since a neutrino mass matrix induced in the model has a constrained texture with limited parameters, it can give a prediction. If we impose neutrino oscillation data to fix those parameters, a value of $\sinθ_{13}$ can be determined. We also discuss several phenomenological features which are discriminated from the ones of the MSSM.
