(弦)模型建立中的模稳定化:规范通量和环

Moduli stabilization in (string) model building: gauge fluxes and loops

A. P. Braun, A. Hebecker, M. Trapletti

摘要:

我们讨论了在6维超引力模型中,规范通量、R对称扭曲和非微扰效应的存在下产生的模稳定化。我们展示了如何存在的D-项,由于规范通量,是兼容的与gaugino凝聚,这两个效果,结合R-对称扭曲,稳定所有的Kaehler模量存在于模型中,在KKLT的精神。我们还计算了来自带电超多重态的标量势的磁通诱导单圈修正,发现它不会使最小值不稳定。

英文摘要:

We discuss the moduli stabilization arising in the presence of gauge fluxes, R-symmetry twists and non-perturbative effects in the context of 6-dimensional supergravity models. We show how the presence of D-terms, due to the gauge fluxes, is compatible with gaugino condensation, and that the two effects, combined with the R-symmetry twist, do stabilize all the Kaehler moduli present in the model, in the spirit of KKLT. We also calculate the flux-induced one-loop correction to the scalar potential coming from charged hypermultiplets, and find that it does not destabilize the minimum.
