:利用之前 T 6 / Z ' 6 上相交 D6 膜模型的统计结果,我们分析了类似于超对称标准模型的规范组和物质含量的解。特别是隐藏扇区的结构、规范耦合常数和手性外来物质含量,在此背景下针对所有可能的标准模型配置进行计算和分类。事实证明,手性奇异子、希格斯粒子的数量和规范耦合的值密切相关。详细讨论了超对称标准模型的手性谱加上类矢量态和无质量 U(1) B − L 的一些例子。
: Using previous results on the statistics of intersecting D6-brane models on T 6 / Z ′ 6 we analyse solutions that resemble the gauge group and matter content of the supersymmetric standard model. In particular the structure of the hidden sector, the gauge coupling constants and chiral exotic matter content are computed and classified for all possible standard model-like configurations on this background. It turns out that the number of chiral exotics, Higgses and values of gauge couplings are strongly correlated. Some examples with the chiral spectrum of the supersymmetric standard model plus vector-like states and a massless U(1) B − L are discussed in detail.
