渐近安全引力中的规范层次问题--复活机制
Gauge hierarchy problem in asymptotically safe gravity--the resurgence mechanism
摘要：
规范层次问题可以在量子引力的渐近安全的情况下找到一个解决方案。我们讨论了一个“复苏机制”，负责希格斯标量质量的运行无量纲耦合首先在紫外区减少，随后在红外区增加。引力诱导的大反常尺寸在普朗克尺度之外的紫外区所需的“自调谐临界性”中起着至关重要的作用。
英文摘要：
The gauge hierarchy problem could find a solution within the scenario of asymptotic safety for quantum gravity. We discuss a "resurgence mechanism" where the running dimensionless coupling responsible for the Higgs scalar mass first decreases in the ultraviolet regime and subsequently increases in the infrared regime. A gravity induced large anomalous dimension plays a crucial role for the required "self-tuned criticality" in the ultraviolet regime beyond the Planck scale.
