论文摘要

我们证明,在设置两个组件的暗物质(DM)中,当DM $ _1 $与热浴之间平衡时,尽管与SM粒子的互动微弱或可忽略不计,但可以通过与DM $ _1 $ _1 $ a $相互互动来使其他DM $ _2 $平衡。我们建议将这种DM候选者(DM $ _2 $)归类为具有独特的冻结特性的称为pseudo-fimp(PFIMP)的类别,该类别依赖于热DM合作伙伴。该草案以独立模型的方式从通用耦合的玻尔兹曼方程(CBEQ)详细阐述了PFIMP性质,然后进行混凝土模型插图。

We demonstrate that in a two component dark matter (DM) set up, when DM$_1$ is equilibrated with the thermal bath, the other DM$_2$, in spite of having feeble or negligible interaction with the SM particles, can be brought to equilibrium just by having sizeable interaction with DM$_1$. We propose that such DM candidates (DM$_2$) should be classified into a category called pseudo-FIMP (pFIMP) having unique freeze-out characteristics which depend on the thermal DM partner. The draft elaborates upon the pFIMP properties from a generic coupled Boltzmann Equations (cBEQ) in a model independent way, followed by a concrete model illustration.
