我们研究杂种优势弦理论中可观察扇区和隐藏扇区的属性之间可能的相关性。具体来说，我们分析了 Z6-II 轨道压缩的情况，它产生了大量具有超对称标准模型谱的模型。我们发现，需要真实的特征确实会影响隐藏扇区，因此隐藏扇区规范组因子 SU(4) 和 SO(8) 受到青睐。在高吉诺凝聚的背景下，这意味着低能超对称破缺。
We study possible correlations between properties of the observable and hidden sectors in heterotic string theory. Specifically, we analyze the case of the Z6-II orbifold compactification which produces a significant number of models with the spectrum of the supersymmetric standard model. We find that requiring realistic features does affect the hidden sector such that hidden sector gauge group factors SU(4) and SO(8) are favored. In the context of gaugino condensation, this implies low energy supersymmetry breaking.
