亚稳通量空间与de Sitter空间

Metastable Flux Configurations and de Sitter Spaces

Katrin Becker, Yu-Chieh Chung, Guangyu Guo

摘要:

本文导出了Calabi-Yau三重上的IIB型弦论紧化中控制复结构模和公理子动力学的无标度标量势临界点的稳定性条件。我们讨论一个T^6定向褶皱的具体例子。然后,我们考虑的四维理论从紧化的IIB型弦论的非几何背景下,这是刚性卡-丘流形的镜像,并表明,复杂的结构模场可以稳定的H_{RR}只,即不需要orientifold投影。在弱耦合下,所有场的稳定化,包括轴对称子,可能需要在H_{NS}通量或标量势修正的情况下打破超对称性。

英文摘要:

We derive stability conditions for the critical points of the no-scale scalar potential governing the dynamics of the complex structure moduli and the axio-dilaton in compactifications of type IIB string theory on Calabi-Yau three-folds. We discuss a concrete example of a T^6 orientifold. We then consider the four-dimensional theory obtained from compactifications of type IIB string theory on non-geometric backgrounds which are mirror to rigid Calabi-Yau manifolds and show that the complex structure moduli fields can be stabilized in terms of H_{RR} only, i.e. with no need of orientifold projection. The stabilization of all the fields at weak coupling, including the axio-dilaton, may require to break supersymmetry in the presence of H_{NS} flux or corrections to the scalar potential.
