IIB/F型理论中的模稳定性与暴胀

Moduli Stabilization and Inflation in Type IIB/F-theory

Ignatios Antoniadis, Yifan Chen, George K. Leontaris

摘要:

在这个演讲的第一部分,一个简短的概述正在进行的辩论是否存在德西特真空在弦论。在第二部分中,在IIB/F型理论的背景下讨论了模稳定化和通货膨胀。考虑三个相交的$D7$膜通量的配置,它表明,更高的回路效应诱导对数修正的Kähler势可以稳定的Kähler模量在德西特真空。当包含一个新的费耶特-伊利奥普洛斯项时,也有可能产生所需数量的e折叠,并满足慢卷暴胀的条件。

英文摘要:

In the first part of this talk, a short overview of the ongoing debate on the existence of de Sitter vacua in string theory is presented. In the second part, the moduli stabilisation and inflation are discussed in the context of type IIB/F-theory. Considering a configuration of three intersecting $D7$ branes with fluxes, it is shown that higher loop effects inducing logarithmic corrections to the Kähler potential can stabilise the Kähler moduli in a de Sitter Vacuum. When a new Fayet-Iliopoulos term is included, it is also possible to generate the required number of e-foldings and satisfy the conditions for slow-roll inflation.
