我们研究的调解超对称性破缺触发的背景通量在II型弦紧化= 1超对称性。中介的出现是由于一个U（1）矢量多重态耦合到一个隐藏的超对称破缺通量扇区和一个可见的D-膜扇区。所需的内部流形可以通过奇异Calabi-Yau流形的非Kahler分解来构造。然后根据内部空间的全局拓扑性质确定编码U（1）耦合的有效作用量。我们调查合适的本地几何形状的隐藏和可见的部门详细。这包括一个系统的研究orientifold对称性的del Pezzo表面实现紧凑的几何形状后，几何过渡。我们构造紧凑的例子承认实现通量超对称破缺和U（1）调解的关键属性。它们的复曲面实现允许我们分析曲线类的几何形状，并确认隐藏和可见扇区之间的拓扑连接。
We study the mediation of supersymmetry breaking triggered by background fluxes in Type II string compactifications with = 1 supersymmetry. The mediation arises due to an U(1) vector multiplet coupling to both a hidden supersymmetry breaking flux sector and a visible D-brane sector. The required internal manifolds can be constructed by non-Kahler resolutions of singular Calabi-Yau manifolds. The effective action encoding the U(1) coupling is then determined in terms of the global topological properties of the internal space. We investigate suitable local geometries for the hidden and visible sector in detail. This includes a systematic study of orientifold symmetries of del Pezzo surfaces realized in compact geometries after geometric transition. We construct compact examples admitting the key properties to realize flux supersymmetry breaking and U(1) mediation. Their toric realization allows us to analyze the geometry of curve classes and confirm the topological connection between the hidden and visible sector.
