具有一般NS-NS通量的IIA中的环面定向褶皱

Toroidal Orientifolds in IIA with General NS-NS Fluxes

Matthias Ihl, Daniel Robbins, Timm Wrase

摘要:

IIA型环形定向褶皱为模型构建者提供了一个很有前途的工具包,特别是当一个不仅包括来自NS-NS和R-R场强的通常通量,而且还包括与NS-NS三形式通量T对偶的通量时。这些新的成分被称为公制通量和非几何通量,可以帮助稳定模量或导致其他新的功能。在本文中,我们研究了两种方法,这些建设,有效场论或通过环形光纤扭曲在一个环形基地。每一种方法都使我们得到重要的观察结果,特别是在某些情况下四维有效势中存在D项,以及对一般NS-NS通量的量子化进行更微妙的处理。虽然我们的方法是通用的,但我们以T^6/Z_4的定向褶皱为例来说明每种方法。

英文摘要:

Type IIA toroidal orientifolds offer a promising toolkit for model builders, especially when one includes not only the usual fluxes from NS-NS and R-R field strengths, but also fluxes that are T-dual to the NS-NS three-form flux. These new ingredients are known as metric fluxes and non-geometric fluxes, and can help stabilize moduli or can lead to other new features. In this paper we study two approaches to these constructions, by effective field theory or by toroidal fibers twisted over a toroidal base. Each approach leads us to important observations, in particular the presence of D-terms in the four-dimensional effective potential in some cases, and a more subtle treatment of the quantization of the general NS-NS fluxes. Though our methods are general, we illustrate each approach on the example of an orientifold of T^6/Z_4.
