研究了基于非abelian离散对称A_4的有限SU(5)大统一模型。这个模型导致了夸克和轻子质量矩阵的民主结构。在软超对称破缺扇区，对标量三线耦合进行对齐，对软标量质量进行简并，从而解决了超对称性问题。
We study a finite SU(5) grand unified model based on the non-Abelian discrete symmetry A_4. This model leads to the democratic structure of the mass matrices for the quarks and leptons. In the soft supersymmetry breaking sector, the scalar trilinear couplings are aligned and the soft scalar masses are degenerate, thus solving the SUSY flavor problem.
