论文摘要
宇宙射线抗抗树脂子是Astroparticle物理学的强大工具。虽然大部分测得的抗植物与次要来源是一致的，但AMS-02实验的精确数据为我们提供了令人鼓舞的前景，以搜索亚较大的主要成分，例如来自暗物质。在这篇简短的评论中，我们讨论了有关重暗物质的最新限制以及批量$ \ lyssim 100 $ gev的暗物质的暂定信号。我们强调可能影响信号的系统错误的特殊作用。特别是，我们讨论了AMS-02数据中二级生产横截面和相关误差的建模的最新进展，AMS-02数据是源自检测器中宇宙射线吸收的不确定性的主要数据。
Cosmic-ray antiprotons are a powerful tool for astroparticle physics. While the bulk of measured antiprotons is consistent with a secondary origin, the precise data of the AMS-02 experiment provides us with encouraging prospects to search for a subdominant primary component, e.g. from dark matter. In this brief review, we discuss recent limits on heavy dark matter as well as a tentative signal from annihilation of dark matter with a mass $\lesssim 100$ GeV. We emphasize the special role of systematic errors that can affect the signal. In particular, we discuss recent progress in the modeling of secondary production cross sections and correlated errors in the AMS-02 data, the dominant ones originating from uncertainties in the cross sections for cosmic-ray absorption in the detector.
