沼泽地构造网和TCC边界
The web of swampland conjectures and the TCC bound
摘要：
我们考虑沼泽地距离和de Sitter距离，分别为一阶参数$λ$和$c$。受最近的Trans-Planckian审查猜想（TCC）的启发，我们提出了距离猜想的一个推广，它将$λ$限定为$c$的TCC界的一半，即4d中的$λ\geq \frac{1}{2}\sqrt{\frac{2}{3}}$.此外，我们提出了一个对应关系的两个架构，涉及塔质量$m$在一侧的标量位$V$在另一侧示意性地为$m\sim |V|^{\frac{1}{2}}$，在大的距离限制。这些建议提出了标量弱引力猜想的推广，并得到了各种例子的支持。$λ$的下界在文献中的许多情况下被明确地验证。利用十个不同的不通过定理对$c$的TCC界进行了检验，并对$V$的渐近极限进行了分析.特别是，从II型紧化的4d标量势的新结果。
英文摘要：
We consider the swampland distance and de Sitter conjectures, of respective order one parameters $λ$ and $c$. Inspired by the recent Trans-Planckian Censorship conjecture (TCC), we propose a generalization of the distance conjecture, which bounds $λ$ to be a half of the TCC bound for $c$, i.e. $λ\geq \frac{1}{2}\sqrt{\frac{2}{3}}$ in 4d. In addition, we propose a correspondence between the two conjectures, relating the tower mass $m$ on the one side to the scalar potential $V$ on the other side schematically as $m\sim |V|^{\frac{1}{2}}$, in the large distance limit. These proposals suggest a generalization of the scalar weak gravity conjecture, and are supported by a variety of examples. The lower bound on $λ$ is verified explicitly in many cases in the literature. The TCC bound on $c$ is checked as well on ten different no-go theorems, which are worked-out in detail, and $V$ is analysed in the asymptotic limit. In particular, new results on 4d scalar potentials from type II compactifications are obtained.
