具有K3-fibred Calabi-Yau三重紧化的IIB型定向褶皱的四Kahler模稳定化

Four Kahler Moduli Stabilisation in type IIB Orientifolds with K3-fibred Calabi-Yau threefold compactification

Dieter Lust, Xu Zhang

摘要:

我们给出了一个具体的和一致的方法,在具有四个Kahler模的IIB型定向折叠紧化中产生一种非微扰超势,包括Gaugino凝聚修正和多瞬子修正.然后利用这种超势以及对Kahler势的Kaprime-correction,将这四个Kahler模全部固定在具有典型K3-正则体积形式的一般Calabi-Yau流形上.在我们的构造中,所考虑的Calabi-Yau三重是K3-可拓的,并且至少允许一个del Pezzo曲面和一个W-曲面。通过对现有的四维自反格多面体的搜索,我们发现其中有23个满足所有要求。

英文摘要:

We present a concrete and consistent procedure to generate one kind of non-perturbative superpotential, including the gaugino condensation corrections and poly-instanton corrections, in type IIB orientifold compactification with four Kahler Moduli. Then we use this kind of superpotential as well as the alphaprime-corrections to Kahler potential to fix all of the four Kahler moduli on a general Calabi-Yau manifold with typical K3-fibred volume form. In our construction, the considered Calabi-Yau threefolds are K3-fibred and admit at least one del Pezzo surface and one W-surface. Searching through all existing four dimensional reflexive lattice polytopes, we find 23 of them fulfilling all the requirements.
