杂种优势Calabi-Yau群的几何模的稳定化

Stabilizing All Geometric Moduli in Heterotic Calabi-Yau Vacua

Lara B. Anderson, James Gray, Andre Lukas, Burt Ovrut

摘要:

我们提出了一个方案,以稳定所有的几何模-即复杂的结构,Kahler模和crackon-在光滑的杂种Calabi-Yau紧化没有Neveu-Schwarz三形式通量。这是使用规范丛所需的任何杂合紧化,其微扰效应的模结合非微扰校正。我们认为,对于适当的规范丛,所有复杂的结构和大量的其他模量可以微扰稳定-在最严格的情况下,只留下一个组合的卡勒模量和作为一个平坦的方向。在这个阶段,剩余的模空间由闵可夫斯基真空组成。也就是说,微扰超势在真空中消失,而不需要微调通量。最后,我们将非微扰效应,如高吉诺凝聚和/或瞬子。这些都受到反常U(1)对称性的强烈约束,而反常U(1)对称性是由所需的丛结构产生的。我们提出了一个具体的例子,与一致的选择的非微扰效应,其中所有剩余的平面方向是稳定的AdS真空。

英文摘要:

We propose a scenario to stabilize all geometric moduli - that is, the complex structure, Kahler moduli and the dilaton - in smooth heterotic Calabi-Yau compactifications without Neveu-Schwarz three-form flux. This is accomplished using the gauge bundle required in any heterotic compactification, whose perturbative effects on the moduli are combined with non-perturbative corrections. We argue that, for appropriate gauge bundles, all complex structure and a large number of other moduli can be perturbatively stabilized - in the most restrictive case, leaving only one combination of Kahler moduli and the dilaton as a flat direction. At this stage, the remaining moduli space consists of Minkowski vacua. That is, the perturbative superpotential vanishes in the vacuum without the necessity to fine-tune flux. Finally, we incorporate non-perturbative effects such as gaugino condensation and/or instantons. These are strongly constrained by the anomalous U(1) symmetries which arise from the required bundle constructions. We present a specific example, with a consistent choice of non-perturbative effects, where all remaining flat directions are stabilized in an AdS vacuum.
