论文摘要
Peccei-Quinn(PQ)对称性对强大的CP问题的有希望的解决方案可能引入质量和层次结构问题,这两者都与Planck物理学有关。在本文中,我们研究了是否可以通过引入满足弱重力猜想(WGC)或其变体的简单隐藏量规组来解释这两个问题。作为一个具体的例子,我们指出,分解为$(n)$的弱耦合的隐藏的$ su(n)$量表对称性可以在塔/子局部WGC的背景下完成这项工作。讨论了宇宙学。
The promising solution to the strong CP problem by a Peccei-Quinn (PQ) symmetry may introduce quality and hierarchy problems, which are both relevant to Planck physics. In this paper, we study whether both problems can be explained by introducing a simple hidden gauge group that satisfies a weak gravity conjecture (WGC) or its variant. As a concrete example, we point out that a weakly-coupled hidden $SU(N)$ gauge symmetry, which is broken down to $SO(N)$, can do this job in the context of a Tower/sub-Lattice WGC. Cosmology is discussed.
