摘要:

我们提出了新的限制暗物质相互作用使用1.7年的COSINE-100数据。COSINE-100实验由106公斤掺铊碘化钠(NaI(Tl))靶材料组成,旨在测试DAMA声称的使用相同的NaI(Tl)探测器观测暗物质。改进的事件选择要求、对探测器背景的更精确理解以及使用更大的数据集大大提高了COSINE-100探测暗物质的灵敏度。没有信号一致的暗物质相互作用的识别,并排除了模型依赖的暗物质的DAMA信号的解释,在特定的背景下,标准晕模型具有相同的NaI(Tl)目标的各种相互作用的假设。

英文摘要:

We present new constraints on dark matter interactions using 1.7 years of COSINE-100 data. The COSINE-100 experiment, consisting of 106 kg of tallium-doped sodium iodide (NaI(Tl)) target material, is aimed at testing DAMA's claim of dark matter observation using the same NaI(Tl) detectors. Improved event selection requirements, a more precise understanding of the detector background and the use of a larger data set considerably enhances the COSINE-100 sensitivity for dark matter detection. No signal consistent with the dark matter interaction is identified, and rules out model-dependent dark matter interpretations of the DAMA signals in the specific context of standard halo model with the same NaI(Tl) target for various interaction hypotheses.
