论文摘要
我们基于标准模型QCD中与介子光谱的类比，介绍了与QCD的黑暗扇区中谐音自我相互作用的模型。对于由两个轻夸克制成的深色介子，我们提出了一个简单的模型，该模型实现了共鸣的自我交流（类似于$ ϕ $ -K-K系统）和热冻结。我们还考虑了由沉重和浅色夸克组成的不对称暗物质，以实现共鸣的自我交流（类似于$υ（4S）$ -B-B系统），并讨论了两个设置的实验探针。最后，我们对SIMP和老年机制中可能内置的可能共鸣的自我互动发表评论，同时利用晶格结果来确定可行性。
We present models of resonant self-interacting dark matter in a dark sector with QCD, based on analogies to the meson spectra in Standard Model QCD. For dark mesons made of two light quarks, we present a simple model that realizes resonant self-interaction (analogous to the $ϕ$-K-K system) and thermal freeze-out. We also consider asymmetric dark matter composed of heavy and light dark quarks to realize a resonant self-interaction (analogous to the $Υ(4S)$-B-B system) and discuss the experimental probes of both setups. Finally, we comment on the possible resonant self-interactions already built into SIMP and ELDER mechanisms while making use of lattice results to determine feasibility.
