通量紧化的扫描:真空结构和软超对称破缺

Scanning the Landscape of Flux Compactifications: Vacuum Structure and Soft Supersymmetry Breaking

摘要:

通过在较大范围内改变通量超势$W_0$的值,我们研究了具有两个K\"ahler模的Calabi-Yau流形$\mathbb{P}^4_{[1,1,1,6,9]}$的通量紧化.我们不包括提升条款。我们发现了AdS和dS真空的丰富的相结构。从$W_0\sim 1$开始,我们再现了指数大体积的情况下,但随着$W_0$减少,出现了新的类的最小值。其中一个对应于超对称KKLT真空,而另一个是一个新的,更深的非超对称极小值。我们研究裸宇宙学常数和软超对称性破缺参数的D7膜上的物质依赖于$W_0$,这些类的极小值。我们讨论了我们的结果的潜在应用。

英文摘要:

We scan the landscape of flux compactifications for the Calabi-Yau manifold $\mathbb{P}^4_{[1,1,1,6,9]}$ with two K\" ahler moduli by varying the value of the flux superpotential $W_0$ over a large range of values. We do not include uplift terms. We find a rich phase structure of AdS and dS vacua. Starting with $W_0\sim 1$ we reproduce the exponentially large volume scenario, but as $W_0$ is reduced new classes of minima appear. One of them corresponds to the supersymmetric KKLT vacuum while the other is a new, deeper non-supersymmetric minimum. We study how the bare cosmological constant and the soft supersymmetry breaking parameters for matter on D7 branes depend on $W_0$, for these classes of minima. We discuss potential applications of our results.
