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毋庸置疑的，然而，即使在暗物质首次发现80年后，所有证据也只是基于大范围的引力效应。经过二十多年的不懈努力，对用来解释暗物质观测的弱相互作用大质量粒子(WIMP)的搜索灵敏度已经达到了与用最基本假设开发的模型的预测很大程度上重叠的水平。在WIMP相互作用的直接搜索中缺乏信号，以及在大型强子对撞机上缺乏新粒子的证据，迫使我们考虑其他模型，而不是粒子物理标准模型的最简单的超对称扩展。
