论文摘要
我们回顾了QCD轴上模型的景观。突出和分类的理论结构将轴质量和耦合范围扩展到传统区域之外。重新检查和更新了宇宙学，天体物理学和实验搜索的范围。
We review the landscape of QCD axion models. Theoretical constructions that extend the window for the axion mass and couplings beyond conventional regions are highlighted and classified. Bounds from cosmology, astrophysics and experimental searches are reexamined and updated.
