Thomas W. Grimm, Tae-Won Ha, Albrecht Klemm, Denis Klevers

摘要:

在具有N=1超对称性的四维F-理论紧化中,描述填充7-膜的时空动力学的场是内部卡-丘四重的复杂结构模空间的一部分。我们在F理论中计算了通量超势,它依赖于所有的复结构模,包括7-膜形变和对应于介子-轴子的场。由于7-膜上的通量诱导5-膜电荷,局部极限允许有效地匹配F-理论的结果,在非紧卡-丘三倍与threeform通量的D5-膜。我们分析了经典和瞬子的贡献,F-理论超势使用镜像对称的卡-丘四重。考虑下的F-理论紧化也承认杂合对偶描述,我们讨论了在这种非微扰对偶的模的识别。

英文摘要:

In four-dimensional F-theory compactifications with N=1 supersymmetry the fields describing the dynamics of space-time filling 7-branes are part of the complex structure moduli space of the internal Calabi-Yau fourfold. We explicitly compute the flux superpotential in F-theory depending on all complex structure moduli, including the 7-brane deformations and the field corresponding to the dilaton-axion. Since fluxes on the 7-branes induce 5-brane charge, a local limit allows to effectively match the F-theory results to a D5-brane in a non-compact Calabi-Yau threefold with threeform fluxes. We analyze the classical and instanton contributions to the F-theory superpotential using mirror symmetry for Calabi-Yau fourfolds. The F-theory compactifications under consideration also admit heterotic dual descriptions and we discuss the identification of the moduli in this non-perturbative duality.
