The existence of dark matter is largely undisputed, yet even 80 years after its first discovery all evidence is based on gravitational effects on large scales only. After more than two decades of dedicated effort, the sensitivity of searches for Weakly Interacting Massive Particles (WIMPs) proposed to explain the dark matter observations has reached a level that overlaps largely with the prediction of models developed with the most basic assumptions. The lack of a signal in direct searches for WIMP interactions as well as the lack of evidence for new particles at the LHC forces us to consider models other than the simplest SuperSymmetric extensions of the standard model of particle physics.

暗物质的存在在很大程度上是无可争议的，但即使在首次发现80年后，所有的证据都是基于大尺度的引力效应。经过二十多年的努力，寻找弱相互作用大质量粒子（WIMPs）来解释暗物质观测的灵敏度已经达到了一个水平，与最基本假设的模型预测基本重叠。在直接寻找WIMP相互作用时缺乏信号，以及在LHC中缺乏新粒子的证据，迫使我们考虑粒子物理标准模型的最简单超对称扩展之外的模型。
