论文摘要
研究了发条轴的超对称性的含义。超对称性可确保萨克斯群岛和轴线具有与发条轴相同的耦合层次结构模式。如果我们假设超对称性断裂在发条位点上是通用的，则将保留耦合结构，而萨克西族和轴那群的质量顺序取决于超对称性断裂量表。虽然巨大的萨克森族和轴迅速衰减，但最轻的轴是可以稳定，因此是候选暗物质的。热产生的轴承深色物质的遗物丰度主要取决于正常质量排序中较重的Axinos的衰减。与传统的轴那场景相比，这指数级增强了热产率。讨论了一些宇宙学问题。
Implications of supersymmetrizing the clockwork axions are studied. Supersymmetry ensures that the saxions and axinos have the same pattern of the coupling hierarchy as the clockwork axions. If we assume supersymmetry breaking is universal over the clockwork sites, the coupling structure is preserved, while the mass orderings of the saxions and axinos can differ depending on the supersymmetry breaking scale. While the massive saxions and axions quickly decay, the lightest axino can be stable and thus a dark matter candidate. The relic abundance of the axino dark matter from thermal production is mostly determined by decays of the heavier axinos in the normal mass ordering. This exponentially enhances the thermal yield compared to the conventional axino scenarios. Some cosmological issues are discussed.
