我们研究了由超对称的Yang-Mills磁化奥氏球理论导出的Yukawa矩阵的结构，它可以实现观测到的夸克和带电轻子质量比以及Cabibbo-Kobayashi-Maswaka(CKM)的混合角，即使只有少量的可调参数，也不需要任何关键的微调。作为原因，我们发现所得到的汤川矩阵具有类似Froggatt-Nielsen的高斯型结构，这为它们提供了一种符合实验数据的合适的织构。
We study the structure of Yukawa matrices derived from the supersymmetric Yang-Mills theory on magnetized orbifolds, which can realize the observed quark and charged lepton mass ratios as well as the Cabibbo-Kobayashi-Maswaka (CKM) mixing angles, even with a small number of tunable parameters and without any critical fine-tuning. As a reason behind this, we find that the obtained Yukawa matrices possess a Froggatt-Nielsen-like structure with Gaussian hierarchies, which provides a suitable texture for them favored by the experimental data.
