我们回顾了超对称性破缺对弦真空造成的戏剧性后果的一些方面。我们特别关注具有破缺或不具有超对称性的十维弦模型中的真空稳定性问题,其微扰谱不含快子。在制定了相关模型后,我们引入了它们的统一低能有效描述,并提出了经典运动方程的许多真空解。此外,我们还对之前德西特真空在翘曲通量致密化中的不通过结果进行了概括。然后我们分析这些真空的经典稳定性和量子稳定性,研究线性场波动和气泡成核。然后,我们描述了如何根据膜动力学来构建由此产生的不稳定性,特别检查膜相互作用、反反应几何形状,并根据最近的提案对膜世界弦结构进行评论。在提供总结后,我们对未来可能的发展提出了一些看法。
We review some aspects of the dramatic consequences of supersymmetry breaking on string vacua. In particular, we focus on the issue of vacuum stability in ten-dimensional string models with broken, or without, supersymmetry, whose perturbative spectra are free of tachyons. After formulating the models at stake, we introduce their unified low-energy effective description and present a number of vacuum solutions to the classical equations of motion. In addition, we present a generalization of previous no-go results for de Sitter vacua in warped flux compactifications. Then we analyze the classical and quantum stability of these vacua, studying linearized field fluctuations and bubble nucleation. Then, we describe how the resulting instabilities can be framed in terms of brane dynamics, examining in particular brane interactions, back-reacted geometries and commenting on a brane-world string construction along the lines of a recent proposal. After providing a summary, we conclude with some perspectives on possible future developments.
