从A4 Flavor对称性到最小重正化SUSY SU(5)具有三重极大混合的大统一模型

Toward minimal renormalizable SUSY SU(5) Grand Unified Model with tribimaximal mixing from A4 Flavor symmetry

Paolo Ciafaloni, Marco Picariello, Emilio Torrente-Lujan, Alfredo Urbano

摘要:

我们解决的问题,合理化的费米子质量和混合的模式,通过添加一个非阿贝尔味对称在一个大统一框架。为此,我们将A4味对称性纳入统一的可重整化SUSY GUT SU(5)模型。借助“II型跷跷板”机制,我们能够通过所谓的tribimalamartum矩阵以自然的方式获得所观察到的中微子混合模式。

英文摘要:

We address the problem of rationalizing the pattern of fermion masses and mixings by adding a nonabelian flavor symmetry in a grand unified framework. With this purpose, we include an A4 flavor symmetry into a unified renormalizable SUSY GUT SU(5) model. With the help of the "Type II Seesaw" mechanism we are able to obtain the pattern of observed neutrino mixings in a natural way, through the so called tribimaximal matrix.
