所谓的超对称风味和CP问题与风味的起源密切相关，因此也与标准模型汤川耦合本身的起源密切相关。我们证明了具有自发CP违背的现实SU(3)风味对称正确地再现了标准模型汤川矩阵，可以同时解决这两个问题，而无需对超对称模型进行特别修改。我们分析了这些模型中的轻子电偶极矩和轻子风味破坏过程。我们表明，如果在大型强子对撞机上可以测量色子质量，那么电子电偶极矩和衰变{mu}{产率}{gamma}自然在提出的实验范围内。
The so-called supersymmetric flavor and CP problems are deeply related to the origin of flavor and hence to the origin of the standard model Yukawa couplings themselves. We show that realistic SU(3) flavor symmetries with spontaneous CP violation reproducing correctly the standard model Yukawa matrices can simultaneously solve both problems without ad hoc modifications of the supersymmetric model. We analyze the leptonic electric dipole moments and lepton flavor violation processes in these models. We show that the electron electric dipole moment and the decay {mu}{yields}e{gamma} are naturally within reach of the proposed experiments if the sfermion masses are measurable at the LHC.
