论文摘要
如果暗物质由新的基本颗粒组成，那么地球周围的轨道运动可能会导致这些颗粒在陆地检测器中相互作用的速率的年度调节。 Dama合作以12 $σ$置信度确定，例如其事件率的年度调制。先前提出的解释是“等离子体暗物质”（例如镜面暗物质），它会通过动力学混合而在检测器中带有电子后坐力。我们对这种等离子体暗物质模型的拟合测试的卡方优点对达马/天秤座调制幅度进行了拒绝等离子体暗物质的假设，作为对该数据的解释，以大于7 $σ$的解释。
If dark matter is composed of new fundamental particles, Earth's orbital motion around the Sun may induce an annual modulation in the rate at which these particles interact in a terrestrial detector. The DAMA collaboration has identified at a 12$σ$ confidence level such an annual modulation in their event rate. One previously proposed explanation is `plasma dark matter' (e.g. mirror dark matter) which would have electron recoils in the detector from interactions via kinetic mixing. We perform a chi-squared goodness of fit test of this plasma dark matter model to DAMA/LIBRA modulation amplitude which rejects the hypothesis of plasma dark matter as an explanation of this data at greater than 7$σ$.
