我们在基于超对称性自发破缺的规范群 SU(3) × SU(2) × U(1) × G ̃ 的模型中研究了夸克及其标量超伙伴的一般质量矩阵的对角化。我们描述了一类模型，其中质量本征态基础中出现的 Cabibbo-Kobayashi-Maskawa 酉矩阵在高吉诺中与矢量玻色子耦合中是相同的。与一般情况不同，从诱导风味改变中性相互作用的角度来看，此类模型似乎是安全的。
We study the diagonalization of the general mass matrix for quarks and their scalar superpartners in models based on a gauge group SU(3) × SU(2) × U(1) × G ̃ with spontaneous breakdown of supersymmetry. We characterize a class of models where the Cabibbo-Kobayashi-Maskawa unitary matrices occuring in the mass-eigenstate basis are the same in the gaugino as in the vector boson couplings. Unlike the general case, this class of models appears to be safe from the point of view of induced flavour changing neutral interactions.
