论文摘要
我们介绍了超谐音的暗物质,这是一种基于超对称QCD的低能量有效理论的自我相互作用的暗物质模型。该理论的结构确保了低能量介子的自我互动的共鸣增强,因为它们的质量比是由颜色和风味的数量来确定的。共鸣增强的自我互动的速度依赖性使这些理论可容纳由不同尺寸的暗物质光环产生的小规模结构的难题。然后,暗物质质量被预测为3-4 MEV,其丰度是通过动力学混合的深色光子通过冻结设置的。
We introduce Super-Resonant Dark Matter, a model of self-interacting dark matter based on the low energy effective theory of supersymmetric QCD. The structure of the theory ensures a resonant enhancement of the self-interactions of the low energy mesons, since their mass ratio is set by the number of colors and flavors. The velocity dependence of the resonantly enhanced self-interactions allows such theories to accommodate puzzles in small scale structure that arise from dark matter halos of different sizes. The dark matter mass is then predicted to be around 3-4 MeV, with its abundance set by freeze-in via a kinetically mixed dark photon.
