论文摘要
强大的CP问题的奇偶校验解决方案是基于Peccei-Quinn对称性的方法的令人信服的替代方法，特别是考虑到量子重力理论中预期违反全局对称性的情况。这些解决方案中最自然的人以低尺度破坏了奇偶校验，从而产生了许多实验可访问的信号。我们根据LHC数据和风味限制来评估最简单的基于平价解决方案的状态，从而突出了围栏，桌面实验和引力波观测站的近未遇到测试的前景。平等破裂和相关重力效应的起源起着至关重要的作用，为通过EDM和重力波发现了新的途径。这些实验机会强调了广义平价的希望，而不是Peccei-Quinn对称性，是对强大CP问题的强大而可测试的解决方案。
Parity solutions to the strong CP problem are a compelling alternative to approaches based on Peccei-Quinn symmetry, particularly given the expected violation of global symmetries in a theory of quantum gravity. The most natural of these solutions break parity at a low scale, giving rise to a host of experimentally accessible signals. We assess the status of the simplest parity-based solution in light of LHC data and flavor constraints, highlighting the prospects for near-future tests at colliders, tabletop experiments, and gravitational wave observatories. The origin of parity breaking and associated gravitational effects play crucial roles, providing new avenues for discovery through EDMs and gravity waves. These experimental opportunities underline the promise of generalized parity, rather than Peccei-Quinn symmetry, as a robust and testable solution to the strong CP problem.
