摘要
搜寻星系暗物质粒子与原子核散射的实验室实验迄今未能确立发现。我们利用XENON100实验的数据寻找与电子相互作用的暗物质。由于在我们的实验低本底之上没有信号证据，我们排除了多种会诱导电子反冲的代表性暗物质模型。对于与电子的轴矢量耦合，我们排除了在粒子质量 m_chi = 2 GeV/c^2 时截面高于 6x10^(-35) cm^2 的情况。与暗物质晕无关地，我们排除了轻子亲和型(leptophilic)暗物质模型作为长期存在的DAMA/LIBRA信号的解释，例如通过轴矢量相互作用与电子耦合的模型（置信水平4.4 sigma）、镜像暗物质（3.6 sigma）和发光暗物质（4.6 sigma）。
