论文摘要
我们系统地研究了在环形方向上的IIB通量压缩中实现自发CP违规的可能性。我们的详细分析导致在退化的CP破裂和 - 强制性真空中存在平坦的方向,以便对三型通量进行一般选择,这表明通量压缩不足以实现自发的CP违规。此外,四维CP可以嵌入二元性对称性中,即用于特定通量选择的模块化对称性。
We systematically investigate possibilities of realizing the spontaneous CP violation in Type IIB flux compactifications on toroidal orientifolds. Our detailed analysis leads to the presence of flat directions at degenerate CP-breaking and -conserving vacua for a generic choice of three-form fluxes, indicating that flux compactifications are not sufficient to realize the spontaneous CP violation. Furthermore, the four-dimensional CP can be embedded into the duality symmetries, namely modular symmetries for a particular choice of fluxes.
