论文摘要
近二十年来，Dama的合作一直在观察到与我们银河系中暗物质存在预期的调制信号。但是，用深色物质颗粒的标准假设对此进行解释是由许多其他实验强烈排除的。可以通过为暗物质模型和感兴趣的属性做出更量身定制的选择来放松这种张力，但是以这种方式扩展感兴趣的模型使得无法最终测试Dama调制。为了理解该信号的确切性质，我们需要基于相同目标（NAI（TL））的检测器，该检测器对与Dama完全相同的粒子相互作用模型敏感。旨在执行此操作的数据或调试阶段中有许多这样的实验，其中两个（Anais和Cosine）最近在数据获取3年后发布了结果。有趣的是，两个实验观察到的调制彼此偏离2 $σ$，而在达马结果的3 $σ$之内。本文解决了基于NAI（TL）的检测器之间的潜在差异，这可能导致迄今为止不同的结果，并特别关注淬火因子。
For nearly two decades the DAMA Collaboration has been observing a modulating signal compatible with that expected from a dark matter presence in our galaxy. However, interpretations of this with the standard assumptions for dark matter particles are strongly ruled out by a large number of other experiments. This tension can be relaxed somewhat by making more tailored choices for the dark matter model and properties of interest, but expanding the models of interest in such a way makes it impossible to test the DAMA modulation conclusively. In order to understand the exact nature of this signal, we need to use a detector based on the same target (NaI(Tl)), which would be sensitive to exactly the same particle interaction models as DAMA. There are a number of such experiments in the data taking or commissioning stages designed to do just this, two of which (ANAIS and COSINE) recently released their results after 3 years of data taking. Interestingly, the modulation observed by the two experiments deviate from each other by 2$σ$, while being within 3$σ$ of the DAMA result. This paper addresses potential differences between NaI(Tl) based detectors that could lead to the differing results to date, with a particular focus on the quenching factor.
