论文摘要
在许多天体物理和陆地环境中，已经观察到了超过预期背景的有趣信号，这可能具有暗物质的起源。天体物理过剩包括Fermi Gamma-ray空间望远镜检测到的银河系中心GEV伽马射线过剩，AMS抗抑制剂和正电子过量，以及511和3.5 KEV X射线线。直接检测过剩包括DAMA/LIBRA年度调制信号，Xenon1t过量和固态检测器中的低阈值过量。我们讨论解决这些过剩的途径，该领域可能会在未来几年内采取行动。
Intriguing signals with excesses over expected backgrounds have been observed in many astrophysical and terrestrial settings, which could potentially have a dark matter origin. Astrophysical excesses include the Galactic Center GeV gamma-ray excess detected by the Fermi Gamma-Ray Space Telescope, the AMS antiproton and positron excesses, and the 511 and 3.5 keV X-ray lines. Direct detection excesses include the DAMA/LIBRA annual modulation signal, the XENON1T excess, and low-threshold excesses in solid state detectors. We discuss avenues to resolve these excesses, with actions the field can take over the next several years.
