暗物质间接探测和对撞机探测实验现状

综述了暗物质间接探测和对撞机探测实验的现状和最新进展,并对现有主要实验的最新结果和限制进行了归纳总结。自2008年以来,宇宙线正负电子谱的反常超出被多个实验组相继报道出来。尽管存在一些争议,暗物质效应是这些超出现象的一种自然解释。另一方面,反质子-质子比和γ射线观测结果均未呈现反常信号,这为暗物质的性质给出很强的限制。此外,也可以通过对撞机探测实验上的零信号来限制暗物质性质。在不久的将来,AMS-02和LHC的新数据可能会为暗物质研究提供新的启示。

Status of Dark Matter Indirect Detection and Collider Detection Experiments

The current status and recent progress of dark matter indirect detection and collider detection experiments are briefly reviewed.The main results and constraints of new experiments are shown.Since 2008,anomalous excesses of cosmic-ray electron and positron spectra have been reported by several experiment collaborations.Despite of some arguments,these excesses can be explained naturally by dark matter effect.On the other hand,both antiproton to proton ratio and gamma-ray results show no anomalous signal and give strong constraints on dark matter.Additionally,constraints on dark matter can be derived from the zero signals from collider detection experiments.In the near future,new results of AMS-02 and LHC may give us some inspirations for dark matter researches.
