论文摘要
我们得出了轴心宇宙学的两个特征，它们可能具有宇宙学的影响，无论轴是否是暗物质：对于允许的轴支质量的全部范围，宇宙轴心背景的演变允许大型CP违反，直到低至$ \ sim $ 2 GEV的温度低至$ \ sim $ 2 GEV，并且一旦轴支磁场就可以在轴上启动轴向轴承的水平，从而启动了轴向轴承的底层，从而使轴向轴向固定的距离，轴向轴向轴承的底层旋转，可以使轴心轴承的良好轴承范围的水平，从而使轴心轴向轴承的临时轴承范围的水平，从而启动了轴心轴向的范围。随时间变化的CP违规。在这两个时期，违反参数$ \barθ$的强CP可以与O（1）一样大。
We derive two features of axion cosmology that may have cosmological implications, whether or not axions are dark matter: For the full range of allowed axion masses, the evolution of a cosmic axion background allows large CP violation until temperatures as low as $\sim$ 2 GeV, and once the axion field begins to oscillate, the cosmological axion field's relaxation to its ground state can briefly provide a new departure from thermal equilibrium, via time-varying CP violation. During both of these periods, the Strong CP violating parameter $\barθ$ can be as large as O(1).
