In the supersymmetric unification model, in which the massless sector contains extra particles beyond those in MSSM, there appear state-mixings between quarks(loptons) and extra particles. We showed that the nontrivial texture of the CKM matrix of quarks emerges as a consequence of the mixings between the down-type quarks and colored Higges. In the lepton sector, although these occur mixings between leptons and down-type Higges, seesaw mechanism and hierarchical Majorana masses play an essential role in the MNS matris. The significant difference between the MNS matrix and the CKM matrix. Is naturally understood in the framework of the string inspired SU(6) × SU(2)ィイD2RィエD2model. SUSY breaking parameters which are expected to be universal, are closely linked to the mediation mechanisms of SUSY breaking.. We proposed a new model of mediating SUSY breaking in the context of the weakly coupled heterotic string. The breakdown of SUSY in the hidden sector is transmitted to anti-generation fields via gravitational interactions. Subsequent transmission of the breaking to the MSSM sector occurs via gauge interactions. It is shown that the mass spectra of superparticles are phenomenologically viable.

在超对称统一模型中，无质量扇区除了在MSSM中包含额外粒子外，还存在夸克（lopton）和额外粒子之间的状态混合。我们证明了夸克的CKM矩阵的非平凡结构是下型夸克和有色希格斯混合的结果。在轻子区，虽然轻子和下型希格斯粒子之间存在混合，但跷跷板机制和分层马约拉纳质量在MNS矩阵中起着至关重要的作用。MNS矩阵与CKM矩阵的显著性差异。自然理解为在弦的框架下启发SU(6) × SU(2) D2R d2模型。超对称性破断参数与超对称性破断的调解机制密切相关，有望具有普适性。在弱耦合异质弦的背景下，我们提出了一个调解超对称性断裂的新模型。超对称性在隐藏扇区的击穿通过引力相互作用传递到反产生场。随后通过仪表相互作用将断裂传输到MSSM扇区。证明了超粒子的质谱在现象学上是可行的。
