来自暗物质湮灭的反物质和γ射线

Antimatter and Gamma-rays from Dark Matter Annihilation

Lars Bergstrom

摘要:

简要回顾了暗物质的间接探测特征。特别是,暗物质粒子湮灭反物质和γ射线的检测方法进行了审查。随着GLAST卫星即将发射,在几GeV到300 GeV的能量范围内的一个关键窗口将打开。该仪器良好的角度和能量分辨率意味着可以搜索冷暗物质模型预测的结构。如果目前对晕暗物质结构的理解是正确的,目前计划的大型地基成像切伦科夫望远镜阵列可能会进一步改善极限,或发现信号。

英文摘要:

A brief review of the indirect detection signatures of dark matter is given. In particular, detection methods of dark matter particle annihilation to antimatter and gamma-rays are reviewed. With the GLAST satellite soon to be launched, a crucial window in the energy range of a few GeV up to 300 GeV will open. The good angular and energy resolution of the instrument means that structures predicted by cold dark matter models can be searched for. Large, currently planned ground-based imaging Cherenkov telescope arrays, may further improve the limits, or discover a signal, if the current understanding of halo dark matter structure is correct.
