我们已经将具有三个家族的中微子质量矩阵的纹理嵌入到MaVans场景中。我们利用加速器场的幂率势和由D4对称性导出的活跃中微子的典型结构，预测了大气中微子和消失的Ue3的最大混合。利用目前的宇宙学数据和地面中微子的实验数据，研究了暗费米子和活跃中微子之间的耦合效应。研究发现，中微子味道混合物随着中微子质量的增加而演化。特别是由于暗费米子和活跃中微子之间的耦合，Ue3演化为非零态，θ大气压偏离了最大混合值。
We have embedded the texture of the neutrino mass matrix with three families into the MaVaNs scenario. We take the power-law potential of the acceleron field and a typical texture of active neutrinos, which is derived by the D4 symmetry and predicts the maximal mixing of the atmospheric neutrino and the vanishing Ue3. The effect of couplings among the dark fermion and active neutrinos are studied by putting the current cosmological data and the terrestrial neutrino experimental data. It is found that the neutrino flavor mixings evolve as well as the neutrino masses. Especially, Ue3 develops into the non-vanishing one and θatm deviates from the maximal mixing due to couplings among the dark fermion and active neutrinos.
