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.
我们研究了杂化弦理论中可观测部分与隐藏部分性质之间的可能关联。具体而言,我们分析了Z6-II轨形紧致化的情况,它产生了大量具有超对称标准模型能谱的模型。我们发现,要求具有现实特征确实会影响隐藏部分,使得隐藏部分规范群因子SU(4)和SO(8)受到青睐。在规范微子凝聚的背景下,这意味着低能超对称破缺。
