论文摘要
假设存在EV或KEV量表无菌中微子，我们使用$ a_4 \ times z_4 \ times z_2 $对称组开发了3+1个中微子质量模型。三个higgs $ h，h^{\ prime} $和$ h^{\ prime \ prime} $被认为给出了所需的中微子质量矩阵，该中微子质量矩阵会生成非零$θ_{13} $。该模型可以提供良好在实验3 $σ$边界内的中微子混合参数。我们还计算了$ 4 \ times 4 $ Active-Sterile中微子混合矩阵，并且发现它与实验边界一致。
Assuming the existence of an eV or KeV scale sterile neutrino, we develop a 3+1 neutrino mass model using $A_4\times Z_4 \times Z_2$ symmetry group. Three Higgs $H, H^{\prime}$ and $H^{\prime\prime}$ are considered to give a desired neutrino mass matrix which generates non-zero $θ_{13}$. The model can give neutrino mixing parameters that are well within the experimental 3$σ$ bounds. We also calculate the $4\times 4$ active-sterile neutrino mixing matrix, and it is found to be consistent with experimental bounds.
