论文摘要
十个维度的超弦理论允许以弦乐为代价以受控的minkowski背景为代价，以弦刻度破裂。 Dudas和Mourad发现的临近最大对称背景涉及扭曲的紧凑型，上面与一个与Codimension-One缺陷相关的间隔。我们通过改变有效的现场理论参数来概括这些解决方案，并讨论间隔的尺寸缩小。特别是，我们表明标量和形式场在一定范围的维度中解散，从而产生了爱因斯坦 - 杨米尔斯理论。此外，我们发现，由于光kaluza-klein模式而引起的这种有效描述的分解反映了Swampland距离的猜想，至少在定性上支持图片的一致性。
Superstring theories in ten dimensions allow spacetime supersymmetry breaking at the string scale at the expense of controlled Minkowski backgrounds. The next-to-maximally symmetric backgrounds, found by Dudas and Mourad, involve a warped compactification on an interval associated with codimension-one defects. We generalize these solutions by varying the effective field theory parameters, and we discuss the dimensional reduction on the interval. In particular, we show that scalars and form fields decouple in a certain range of dimensions, yielding Einstein-Yang-Mills theory. Moreover, we find that the breakdown of this effective description due to light Kaluza-Klein modes reflects the swampland distance conjecture, supporting the consistency of the picture at least qualitatively.
