我们提出了一个超对称模型，其中观察到的费米子质量和混合是通过将三代物质和两个希格斯场定位在紧凑的额外维度中的不同位置来生成的。超对称性被闪耀方法打破，并且打破通过高吉诺中介传达到标准模型场。夸克质量、CKM 混合角和 {mu} 项是通过 {Omicron}(1) 的所有无量纲耦合生成的。除了额外维度的大小（GUT 尺度）之外，所有维度参数均符合五维普朗克尺度。超级伙伴谱具有高度预测性，并且被发现在很宽的参数空间范围内具有中性 LSP。简要讨论了由此产生的现象学和模型的有趣扩展。
We present a supersymmetric model in which the observed fermion masses and mixings are generated by localizing the three generations of matter and the two Higgs fields at different locations in a compact extra dimension. Supersymmetry is broken by the shining method and the breaking is communicated to standard model fields via gaugino mediation. Quark masses, CKM-mixing angles and the {mu} term are generated with all dimensionless couplings of {Omicron}(1). All dimensionful parameters are of order the five-dimensional Planck scale except for the size of the extra dimension which is of order the GUT scale. The superpartner spectrum is highly predictive and is found to have a neutralino LSP over a wide range of parameter space. The resulting phenomenology and interesting extensions of the model are briefly discussed.
