从A4到2 $\leftrightarrow$ 3对称性的质量矩阵模型

Mass Matrix Model Broken From A4 To 2 $\leftrightarrow$ 3 Symmetry

Takeshi Fukuyama

摘要:

2 $\leftrightarrow$ 3对称性是通过从4次交替群($A4$)对称性破缺实现的。$A4$解释了为什么世代数是三。而质量矩阵是以对$2\leftrightarrow 3$对称性$\times Z_3$破缺的形式实现的,这导致我们得到了具有零(1,1)分量的$2\leftrightarrow 3$对称质量矩阵。因此,具有$2\leftrightarrow 3$对称性和零(1,1)分量的$3\times 3$质量矩阵模型具有与大统一模型中的对称性相同的群论背景。

英文摘要:

2$\leftrightarrow$3 symmetry is realized by the breaking from alterating group of degree 4 ($A4$) symmetry. $A4$ explains why the generation number is three. However the mass matrices are realized in the form of the breaking to $2\leftrightarrow 3$ symmetry $\times Z_3$, which leads us to $2\leftrightarrow 3$ symmetric mass matrix with vanishing (1,1) component. Thus the $3\times 3$ mass matrix model with $2\leftrightarrow 3$ symmetry and vanishing (1,1) component has the group theoretical background as the symmetry in GUT model.
