从修正的三重中微子混合矩阵计算非零$θ_{13}$和中微子质量

Nonzero $θ_{13}$ and Neutrino Masses from the Modified Tribimaximal Neutrino Mixing Matrix

Asan Damanik

摘要:

为了适应非零和相对较大的混合角$θ_{13}$,我们通过引入一个简单的扰动矩阵来扰动三重极大混合矩阵,从而对三重极大混合矩阵进行了修正。修正后的TBM能再现非零混合角$θ_{13}=7.9^{0}$,与实验结果一致。通过对修正的全弹道模型得到的中微子质量矩阵施加两个零的纹理,我们得到了正常层次的中微子质量谱。文中还讨论了一些现象学意义

英文摘要:

In order to accommodate nonzero and relatively large of mixing angle $θ_{13}$, we modified the tribimaximal mixing(TBM) matrix by introducing a simple perturbation matrix to perturb TBM matrix. The modified TBM can reproduce nonzero mixing angle $θ_{13}=7.9^{0}$ which is in agreement with the present experimental results. By imposing two zeros texture into the obtained neutrino mass matrix from modified TBM, we then have the neutrino mass spectrum in normal hierarchy. Some phenomenological implications are also discussed
