论文摘要
我们使用最少数量的参数与原始理论的对称性一致，对Altarelli-Feruglio $ a_4 $ a_4 $ a _4 $ a _4 $ a _4 $ a _4 $ a_4 $。所得模型与所有目前有关中微子质量和混合的数据一致。此外，它为未来的实验做出了可测试的预测，旨在改善$ \ sin^2θ_{12} $，$ \ sin^2θ_{13} $，$δ_{\ rm cp} $和中间型双 - 贝塔dbeta depbeta decay参数$ | m _ m _ m _ {eee}。我们的模型利用了在$ A_4 $离散对称性下收取的多个允许的多个允许（质量不同）收缩的独特可能性。
We present a simple modification of the Altarelli-Feruglio $A_4$ flavor symmetry model using a minimal number of parameters congruous with the symmetries of the original theory. The resulting model is consistent with all presently known data on neutrino masses and mixings. Furthermore, it makes testable tight predictions for future experiments aimed at improving the measurements of $\sin^2θ_{12}$, $\sin^2θ_{13}$, $δ_{\rm CP}$ and the neutrinoless double-beta decay parameter $|m_{ee}|$. Our model exploits the unique possibility of multiple allowed, yet qualitatively different, contractions of fields charged under the $A_4$ discrete symmetry.
