非WIMP候选人

Non-WIMP Candidates

Jonathan L. Feng

摘要:

非WIMP暗物质候选者包括由极小性激发的粒子,由实验异常激发的候选者,以及主要由聪明的反传统者的愿望激发的奇异可能性,以突出我们对暗物质的本质是多么的无知。在这篇评论中,我讨论的候选人不是WIMP,但仍然分享相同的理论动机作为WIMP,也自然有正确的遗物密度。有两个类:超级弱相互作用暗物质,其中所需的遗迹密度通过衰变继承;无弱相互作用暗物质,其中暗物质的质量和耦合一起缩放以维持所需的热遗迹密度。

英文摘要:

Non-WIMP dark matter candidates include particles motivated by minimality, candidates motivated by experimental anomalies, and exotic possibilities motivated primarily by the desire of clever iconoclasts to highlight how truly ignorant we are about the nature of dark matter. In this review, I discuss candidates that are not WIMPs, but nevertheless share the same theoretical motivations as WIMPs and also naturally have the correct relic density. There are two classes: superWIMP dark matter, where the desired relic density is inherited through decays, and WIMPless dark matter, where the dark matter's mass and couplings scale together to maintain the desired thermal relic density.
