报道了在寻找质量从1 MeV c^-2−2到1GeV c-2−2的暗物质粒子方面的最新进展。在这个质量范围内的几个候选暗物质有望在直接探测实验中产生可测量的电子反冲信号。我们主要关注半导体探测器中暗物质粒子与电子的散射，因为它们的低电离阈值从根本上具有最高的灵敏度。电荷耦合器件(CCD)硅探测器是领先的技术，预计在未来几年将取得重大进展。我们介绍了ccd计划的现状，并简要报告了其他努力。
We report on recent progress in the search for dark matter particles with masses from 1 Mev c^{-2}−2 to 1 Gev c^{-2}−2. Several dark matter candidates in this mass range are expected to generate measurable electronic-recoil signals in direct-detection experiments. We focus on dark matter particles scattering with electrons in semiconductor detectors since they have fundamentally the highest sensitivity due to their low ionization threshold. Charge-coupled device (CCD) silicon detectors are the leading technology, with significant progress expected in the coming years. We present the status of the CCD program and briefly report on other efforts.
