标题： Velocity-dependent self-interacting dark matter and composite Higgs

摘要： 我们证明了自相互作用暗物质候选者（具体来说是一个狄拉克费米子）的质量可以通过复合动力学生成，并且一个轻标量媒介粒子会作为复合粒子与希格斯玻色子本身一起出现。这些新模型自然地解释了各种尺度上的晕结构问题，并同时缓解了标准模型中的自然性问题。暗物质候选者的遗迹密度是对称的粒子-反粒子，并由于热冻结效应而确定。这些模型是四维规范理论，其中的费米子数量最少，且在新的限制性规范群下带电。最后，我们演示了这些模型满足由暗物质遗迹密度、大爆炸核合成、宇宙微波背景以及直接和间接探测实验所设定的各种约束条件。 显示英文摘要

摘要： We show that the mass of a self-interacting dark matter candidate, specifically a Dirac fermion, can be generated by composite dynamics, with a light scalar mediator emerging alongside the Higgs itself as composite particles. These novel models naturally explain the halo structure problems at various scales and alleviates the Standard Model naturalness problem simultaneously. The relic density of the dark matter candidates is particle anti-particle symmetric and due to thermal freeze-out. These models are four-dimensional gauge theories with a minimal number of fermions charged under a new confining gauge group. Finally, we demonstrate that these models satisfy various constraints set by the dark matter relic density, Big Bang Nucleosynthesis, Cosmic Microwave Background, as well as direct and indirect detection experiments.
