驯服、弦和距离猜想

Tameness, Strings, and the Distance Conjecture

Thomas W. Grimm, Stefano Lanza, Chongchuo Li

摘要:

距离猜想指出,当接近场空间中无限距离的点时,无限的模式塔会变成指数光。我们认为,这种说法的内在路径依赖,可以解决结合距离猜想与最近的驯服猜想。后者断言有效理论由驯服的几何描述,并对耦合函数和场空间实施强有限性约束。通过利用这些驯服的限制,我们认为,该区域附近的无限距离点承认分解成多个部门,其中路径独立的声明相关联的塔的状态可以建立。然后,我们引入了一个更受约束的一类驯服的功能,在最多的多项式渐近增长,并认为他们足以描述已知的弦论有效的行动。值得注意的是,这种功能的多场依赖性可以重建的一维线性测试路径在每个部门的边界附近。在四维有效理论中,这些测试路径被描绘成一组离散的宇宙弦解。这表明这种宇宙弦解可以作为研究任何四维有效场论的近边界场空间区域的有力工具。为了说明这些一般性的意见,我们讨论的中心作用的驯服和宇宙弦的解决方案在卡-丘紧化的IIB型弦论。

英文摘要:

The Distance Conjecture states that an infinite tower of modes becomes exponentially light when approaching an infinite distance point in field space. We argue that the inherent path-dependence of this statement can be addressed when combining the Distance Conjecture with the recent Tameness Conjecture. The latter asserts that effective theories are described by tame geometry and implements strong finiteness constraints on coupling functions and field spaces. By exploiting these tameness constraints we argue that the region near the infinite distance point admits a decomposition into finitely many sectors in which path-independent statements for the associated towers of states can be established. We then introduce a more constrained class of tame functions with at most polynomial asymptotic growth and argue that they suffice to describe the known string theory effective actions. Remarkably, the multi-field dependence of such functions can be reconstructed by one-dimensional linear test paths in each sector near the boundary. In four-dimensional effective theories, these test paths are traced out as a discrete set of cosmic string solutions. This indicates that such cosmic string solutions can serve as powerful tool to study the near-boundary field space region of any four-dimensional effective field theory. To illustrate these general observations we discuss the central role of tameness and cosmic string solutions in Calabi-Yau compactifications of Type IIB string theory.
