论文摘要
使用$ a_ {4} $离散对称组构建具有五个额外标量的修改中微子质量模型。所得的质量基质能够与Trimaximal混合提供必要的偏差，该混合重现了当前的中微子质量并以良好的精度将数据混合。该模型可用于对中准双β衰变参数$ | m_ {ββ} | $的未来测量值进行测试预测。该分析与最新的宇宙学结合$σm_{i} \ leq $ 0.12 ev是一致的。
A modified neutrino mass model with five extra scalars is constructed using $A_{4}$ discrete symmetry group. The resultant mass matrix is able to give necessary deviation from Tribimaximal mixing which reproduces the current neutrino masses and mixing data with good accuracy. The model gives testable prediction for the future measurements of the neutrinoless double-beta decay parameter $|m_{ββ}|$. The analysis is consistent with latest cosmological bound $Σm_{i}\leq$ 0.12 eV.
