摘要：
被称为 Festina Lente (FL) 的沼泽地猜想对准德西特空间中所有带电粒子的质量施加了下界。在本文中，我们提出了 aFL（axionic Festina Lente，轴子化 Festina Lente）界限，即将 FL 扩展至源于 II 型弦理论的轴子样粒子。我们发现瞬子作用量与轴子衰变常数的乘积受到真空能的下界约束。这是间接实现的，通过对卡拉比-丘三维流形进行降维，并将偶极子的 FL 结果转化为纯几何界限。我们讨论了轴子黑洞演化以及 aFL 界限对欧几里得虫洞的约束，表明引力论证无法直接应用于源于轴子的粒子。我们还讨论了 aFL 界限的现象学意义，包括对虫洞暴胀模型和通过动力学混合实现的轴子-光子耦合的约束。
英文摘要：
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.
