在早期宇宙中,一个具有质量间隙的热解耦的隐藏粒子扇区通常会进入一个自相残杀的阶段。标准模型扇区的温度比隐藏扇区的温度要低。我们提出了食人暗物质的框架,其中暗物质驻留在一个蚕食部门的遗迹密度设置为2比2的湮灭。食人暗物质的可观测信号包括间接探测率的提高,新的相对论自由度和温暖的暗物质。
A thermally decoupled hidden sector of particles, with a mass gap, generically enters a phase of cannibalism in the early Universe. The Standard Model sector becomes exponentially colder than the hidden sector. We propose the Cannibal Dark Matter framework, where dark matter resides in a cannibalizing sector with a relic density set by 2-to-2 annihilations. Observable signals of Cannibal Dark Matter include a boosted rate for indirect detection, new relativistic degrees of freedom, and warm dark matter.
