论文摘要
我们研究了一个模块化$ A_4 $不变的双环中微子质量模型在超对称框架中，我们在其中尽可能少地引入新领域，并期望超级零部队对中微子群众的贡献。在正常层次结构的情况下，我们成功地重现了中微子振荡数据，并预测了几个可观察到的物品，例如阶段和中微子质量，集中在模量$τ= i，ω的附近固定点附近的三个特定区域上这些点在弦理论的通量压缩中受到统计上的青睐。我们通过执行全局$χ^2 $分析来显示每个点的几个结果，并以最小$χ^2 $的形式演示基准点。
We investigate a modular $A_4$ invariant two-loop neutrino mass model in a supersymmetric framework, where we introduce new fields as minimum as possible, expecting contributions of superpartners to the neutrino masses. We successfully reproduce the neutrino oscillation data thanks to the superpartner contributions in case of normal hierarchy, and predict several observables such as phases and neutrino masses, concentrating on three specific regions at nearby fixed points of modulus $τ=i,ω,i\times \infty$, where $ω\equiv e^{2πi/3}$. These points are statistically favored in flux compactifications of the string theory. We show several results in each the points by performing global $χ^2$ analysis, and demonstrate benchmark points with the minimum $χ^2$.
