当以特定的方式破坏时，证明了S3symmetry是一种非常好的近似对称性。这在夸克扇区和轻子扇区都成立。打破它的方法是由K-M机制所暗示的，而不是应用于混合矩阵，而是应用于质量矩阵。在夸克扇区，我们有一个几乎完美的拟合实验数据，在轻子扇区，我们有一个精度为θ13。
The S3symmetry is shown to be a very good approximate symmetry when it is broken in a specific way. This is true both in quark sector and in lepton sector. The way to break it is implied by the K–M mechanism applied not to the mixing matrix but to the mass matrices. In quark sector, we have an almost perfect fitting to the experimental data, and in lepton sector, we have a precision for the θ13.
