标题： Axion production via trapped misalignment from Peccei-Quinn symmetry breaking

摘要： Peccei-Quinn（PQ）对称性不需要是完全精确的，甚至一个与QCD异常不一致的极小的PQ破缺源也可能具有重要的物理意义。 在这项研究中，我们考察了一类PQ破缺算符对通过错位产生的轴子宇宙学产额的影响，重点研究了温度相关和无关的PQ破缺势。 特别是，我们展示了被困错位机制的一种变体可以延迟轴子振荡的开始，从而导致一个轴子暗物质窗口，其质量为$m_a \gg 10^{-5}$eV。 这一情景可以通过多种实验方法进行测试，包括标准的轴子腔检测器和轴子望远镜，以及电偶极矩搜索和轴子介导力的研究。 显示英文摘要

摘要： The Peccei-Quinn (PQ) symmetry does not need to be exact, and even a tiny source of PQ breaking not aligned with the QCD anomaly might have significant phenomenological implications. In this study, we examine the effects of a general class of PQ-breaking operators on the axion cosmological production via misalignment, focussing on both temperature-dependent and independent PQ-breaking potentials. In particular, we show that a variant of the trapped misalignment mechanism can delay the onset of axion oscillation, leading to an axion dark matter window with $m_a \gg 10^{-5}$ eV. This scenario is testable through various experimental approaches, including standard axion haloscopes and helioscopes, as well as searches for electric dipole moments and axion-mediated forces.
