我们讨论了在弱耦合IIB型紧化和任意耦合下的F理论模型中嵌入幂零Goldstino扇区的技术,提供了半现实紧化中这两种情况的例子。我们首先展示如何利用局部锥形喉道中的反D3膜来构造幂零Goldstino的局部嵌入,然后讨论如何在全局一致的紧致模型中设计所需的局部结构。我们给出了两个明显的例子,最后一个也支持手征物质和Kähler模稳定化。
A bstractWe discuss techniques for embedding a nilpotent Goldstino sector both in weakly coupled type IIB compactifications and F-theory models at arbitrary coupling, providing examples of both scenarios in semi-realistic compactifications. We start by showing how to construct a local embedding for the nilpotent Goldstino in terms of an anti D3-brane in a local conifold throat, and then discuss how to engineer the required local structure in globally consistent compact models. We present two explicit examples, the last one supporting also chiral matter and Kähler moduli stabilisation.
