$A_4$最小扩展跷跷板机制中的活性-惰性中微子质量和混合

Active-Sterile neutrino masses and mixings in $A_4$ minimal extended seesaw mechanism

M. Kishan Singh, S. Robertson Singh, N. Nimai Singh

摘要:

假设存在eV或KeV尺度的无菌中微子,我们利用$A_4\times Z_4 \times Z_2$对称群建立了一个3+1中微子质量模型。三个Higgs粒子$H, H^{\prime}$和$H^{\prime\prime}$被认为可以给出一个期望的中微子质量矩阵,该矩阵产生非零的$θ_{13}$。该模型可以给出中微子混合参数,这些参数都在实验3 $σ$的范围内。我们还计算了$4\times 4$活跃-无菌中微子混合矩阵,并发现它与实验界是一致的。

英文摘要:

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.
