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，无质量扇区包含超出MSSM的额外粒子，在夸克（Loptons）和额外的颗粒之间出现状态混合。我们表明，夸克的CKM矩阵的非平凡纹理是由于羽绒夸克和彩色的希格斯之间的混合而出现的。在Lepton部门中，尽管这些发生在Leptons和Pown-type Higges之间，Seesaw机制和分层Majorana群众在MNS矩阵中起着至关重要的作用。 MNS矩阵与CKM矩阵之间的显着差异。在字符串启发的SU（6）×SU（2）II D2Rie D2Model的框架中自然了解。 Susy Breaking参数预计将是通用的，与Susy Breaking的中介机制密切相关。.我们提出了一种新的介导SUSY Breaking在弱耦合异源弦的背景下的模型。 SUSY在隐藏区域中的崩溃通过重力相互作用传播到抗生成领域。随后通过仪表相互作用发生断裂到MSSM扇区的传播。结果表明，超级粒子的质谱在现象学上是可行的。
