摘要:

我们提出了带有$Δ(54)$的轻子味模型,它通常出现在$T^2/Z_3$轨道上的杂种优势弦模型中。我们的模型再现了参数区域中简并中微子质量或两个无质量中微子的三双峰混合。我们通过将中微子质量的实验数据放在中微子质量的正常层次中来预测偏离三双峰混合的情况。$\sin^2θ_{13}$的上限为0.01。$θ_{23}$与$θ_{13}$之间存在较强的相关性。除非$θ_{23}$明显偏离最大混合,否则$θ_{13}$仍然很小。

英文摘要:

We present the lepton flavor model with $Δ(54)$, which appears typically in heterotic string models on the $T^2/Z_3$ orbifold. Our model reproduces the tri-bimaximal mixing in the parameter region around degenerate neutrino masses or two massless neutrinos. We predict the deviation from the tri-bimaximal mixing by putting the experimental data of neutrino masses in the normal hierarchy of neutrino masses. The upper bound of $\sin^2θ_{13}$ is 0.01. There is the strong correlation between $θ_{23}$ and $θ_{13}$. Unless $θ_{23}$ is deviated from the maximal mixing considerably, $θ_{13}$ remains to be tiny.
