标题： Non-WIMP Candidates

摘要： 非WIMP暗物质候选者包括由极简性启发的粒子、由实验异常现象启发的候选者以及主要由聪明的反传统主义者希望强调我们对暗物质本质的无知所激发的奇异可能性。 在这篇综述中，我讨论了那些不是WIMP但仍然与WIMP共享相同理论动机，并且自然具有正确的遗迹密度的候选者。这些候选者分为两类：超级WIMP暗物质，其中期望的遗迹密度通过衰变继承；以及WIMPless暗物质，其中暗物质的质量和耦合一起按比例调整以维持期望的热遗迹密度。 显示英文摘要

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.
