| 摘 要： | 本文简介了暗物质间接探测的最新进展.主要介绍近年来PAMELA（Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics）卫星所探测到的宇宙线正电子超出的问题,及相关的理论解释.本文还介绍了PAMELA对于宇宙线反质子的测量结果,ATIC和Fermi卫星对于正负电子总能谱的测量结果等.另一个重要的结果来自于Fermi和地面实验对于伽马射线的测量结果,这些结果对暗物质性质给出较强的限制. |
| 关 键 词： | 暗物质 宇宙线 伽马射线 |

| Abstract: | In this article we introduce the present status of indirect detection of dark matter briefly. Especially we introduce the positron excess detected at PAMELA and the related works to explaining the results. We also introduce the antiproton result by PAMELA and electron/positron spectrum measured by ATIC and Fermi. The gamma ray results by Fermi and ground experiments are introduced. These results give quite strong constraints on the nature of dark matter. |
