我们证明了在具有反常U(1)X对称性的超对称E6大统一模型中,νμ和ντ之间具有大混合的中微子质量是自然再现的.我们提出了一个简单的方案,其中包括一个新的机制称为“E-扭曲”的费米子质量矩阵的所有特征,不仅夸克/轻子狄拉克质量,而且中微子的马约拉纳质量,可以复制,尽管事实上,所有的成员在27个每一代被分配一个共同的U(1)X电荷。
We show that neutrino masses with large mixing between νμ and ντ are naturally reproduced in a supersymmetric E6 grand unification model with an anomalous U(1)X symmetry. We propose a simple scenario which incorporates a novel mechanism called ‘E-twisting’ by which all the characteristic features of the fermion mass matrices, not only the quark/lepton Dirac masses but also the neutrino’s Majorana masses, can be reproduced despite the fact that all the members in 27 of each generation are assigned a common U(1)X charge.
