论文摘要
可以通过测量合适检测器中的靶核或电子散射来直接检测到填充我们银河光环的暗物质颗粒。由于预计这种相互作用的可能性很低，并且会产生非常小的能量沉积，因此检测具有挑战性。正在考虑将独特的签名（例如相互作用速率或方向性的年度调制）分配到可能的观察结果的可能识别。在这里，将提出不同暗物质直接检测实验的物理案例，并将讨论正在应用或考虑的不同和互补的技术，总结其特征和最新结果。将特别关注与TPC相关的项目；目前，使用高贵液体的实验具有限制广泛的暗物质候选物和气态探测器的相互作用横截面的领先作用，这是非常有希望的，可以探索特别低的质量暗物质以及测量方向性。
Dark matter particles populating our galactic halo could be directly detected by measuring their scattering off target nuclei or electrons in a suitable detector. As this interaction is expected to occur with very low probability and would generate very small energy deposits, the detection is challenging; the possible identification of distinctive signatures (like an annual modulation in the interaction rates or directionality) to assign a dark matter origin to a possible observation is being considered. Here, the physics case of different dark matter direct detection experiments will be presented and the different and complementary techniques which are being applied or considered will be discussed, summarizing their features and latest results obtained. Special focus will be made on TPC-related projects; experiments using noble liquids have presently a leading role to constrain interaction cross sections of a wide range of dark matter candidates and gaseous detectors are very promising to explore specifically low mass dark matter as well as to measure directionality.
