关于Kahler模的Swampland距离猜想

The Swampland Distance Conjecture for Kahler moduli

Pierre Corvilain, Thomas W. Grimm, Irene Valenzuela

摘要:

沼泽地距离猜想表明,无限的模式塔在接近场空间中无限适当距离处的点时变成指数光。本文在Calabi-Yau三重紧化的Kähler模空间中研究了这一猜想,并进一步阐明了无限态塔是由与无穷远点相关的离散对称性产生的这一命题.在大体积区域,无限态塔是由局部单值矩阵的作用产生的,并由D-膜电荷的轨道编码。我们表示这些单值矩阵的三重交叉数分类的无限远的点,并构建相关的无限电荷轨道,成为无质量的。然后,我们转向详细研究的椭圆纤维卡-丘三倍的电荷轨道。我们认为,对于这些几何形状的模对称的模空间可以用来转移大体积轨道的小椭圆纤维制度。由此产生的轨道可以用于紧化的M-理论是对偶的F-理论紧化,包括一个额外的圆。特别是,我们表明,总是有电荷轨道满足的距离猜想,对应于卡鲁扎-克莱因塔沿该圆。整合出KK塔在模空间中产生了无限的距离,从而支持了在这种情况下出现的想法。

英文摘要:

The Swampland Distance Conjecture suggests that an infinite tower of modes becomes exponentially light when approaching a point that is at infinite proper distance in field space. In this paper we investigate this conjecture in the Kähler moduli spaces of Calabi-Yau threefold compactifications and further elucidate the proposal that the infinite tower of states is generated by the discrete symmetries associated to infinite distance points. In the large volume regime the infinite tower of states is generated by the action of the local monodromy matrices and encoded by an orbit of D-brane charges. We express these monodromy matrices in terms of the triple intersection numbers to classify the infinite distance points and construct the associated infinite charge orbits that become massless. We then turn to a detailed study of charge orbits in elliptically fibered Calabi-Yau threefolds. We argue that for these geometries the modular symmetry in the moduli space can be used to transfer the large volume orbits to the small elliptic fiber regime. The resulting orbits can be used in compactifications of M-theory that are dual to F-theory compactifications including an additional circle. In particular, we show that there are always charge orbits satisfying the distance conjecture that correspond to Kaluza-Klein towers along that circle. Integrating out the KK towers yields an infinite distance in the moduli space thereby supporting the idea of emergence in that context.
