论文摘要
如果欧几里得虫洞对量子重力的路径积分有意义贡献，它们可能对粒子物理和宇宙学具有重要意义。主要效应是由虫洞产生的，虫洞的大小与有效田间理论的截止尺度相当，紫外线校正变得相关。我们研究了在弦动机的场景中对经典轴虫孔溶液的校正，在这些情况下，轴心的Dilaton伴侣变得巨大。我们发现颈部区域附近的校正与轴弱重力猜想的最新版本一致。
If Euclidean wormholes contribute meaningfully to the path integral of quantum gravity they can have important implications for particle physics and cosmology. The dominant effects arise from wormholes whose sizes are comparable to the cut-off scale of effective field theory, for which ultraviolet corrections become relevant. We study corrections to classical axion wormhole solutions in string motivated scenarios in which the dilaton partner of the axion becomes massive. We find corrections near the neck region which are consistent with a recent version of the weak gravity conjecture for axions.
