论文摘要
被称为festina lente（FL）的Swampland猜想在准灵感保健空间中所有带电的颗粒的质量上施加了一个下限。在本文中，我们提出了AFL（Axionic festina lente）结合，这是由II型字符串理论引起的fl延伸到类似轴突的粒子。我们发现，激体动作和轴衰变常数的乘积是从下面界定的。这是间接实现的，使用尺寸降低卡拉比Yau三倍，并将偶极子的fl结果转换为纯几何结合。我们讨论了轴承黑洞的演变，以及对欧几里得虫洞的AFL约束，表明导致u $ $（1）$带电颗粒的FL结合的重力参数不能直接应用于轴上。此外，我们讨论了AFL结合的现象学含义，包括对弦膨胀模型的约束以及通过动力学混合的轴突 - 光子耦合。
The swampland conjecture known as Festina Lente (FL) imposes a lower bound on the mass of all charged particles in a quasi-de Sitter space. In this paper, we propose the aFL (axionic Festina Lente) bound, an extension of FL to axion-like particles arising from type II string theory. We find that the product of the instanton action and the axion decay constant is bounded from below by the vacuum energy. This is achieved indirectly, using dimensional reduction on Calabi-Yau threefolds, and translating the FL result for dipoles into a purely geometric bound. We discuss axionic black holes evolution, and aFL constraints on Euclidean wormholes, showing that the gravitational arguments leading to the FL bound for U$(1)$ charged particles cannot be directly applied to axions. Moreover, we discuss phenomenological implications of the aFL bound, including constraints on string inflation models and the axion-photon coupling via kinetic mixing.
