摘要：

这是2012年版粒子数据组的粒子性质评论中关于暗物质的迷你评论。在简要总结了支持暗物质存在的论点后，我们列出了可能的候选者，质量从几分之一eV（例如，轴子）到许多太阳质量（例如，原始黑洞），并讨论探测它们的方法。主要重点是弱相互作用大质量粒子（WIMPs）。国际社会正在作出巨大努力，以直接探测它们，或者探测它们的湮灭产物。我们解释了为什么我们认为所有的声明已经建立了一个积极的信号，无论是直接或间接的检测是不成熟的。我们还介绍了一个{ \it WIMP安全}的最小质量的概念，低于这个质量，一个给定的直接搜索实验的解释强烈依赖于尾部的WIMP速度分布和/或实验能量分辨率。

英文摘要：

This is the mini-review on Dark Matter in the 2012 edition of the Particle Data Group's Review of Particle Properties. After briefly summarizing the arguments in favor of the existence of Dark Matter, we list possible candidates, ranging in mass from a fraction of an eV (e.g., axions) to many solar masses (e.g., primordial black holes), and discuss ways to detect them. The main emphasis is on Weakly Interacting Massive Particles (WIMPs). A large international effort is being made to detect them directly, or else to detect their annihilation products. We explain why we consider all claims to have established a positive signal for WIMPs in either direct or indirect detection to be premature. We also introduce the concept of a {\it WIMP safe} minimal mass; below this mass, the interpretation of a given direct search experiment depends strongly on the tail of the WIMP velocity distribution and/or on the experimental energy resolution.
