论文摘要
我们表明,可以通过相对较低的质量发光暗物质候选者来解释Xenon1t实验的电子后坐力事件的过量。暗物质在检测器(或周围的岩石)中不足地散布,以产生较重的黑暗状态,〜2.75 keV质量分裂。然后,这种较重的状态在检测器内腐烂,在电子后坐力光谱中产生峰值,这非常适合观察到的过量。我们评论未来直接检测数据集将该模型与超出标准模型方案之外的其他模型区分开的能力,以及与可能的tri缩影背景(包括使用昼夜调制,多通道信号等)的能力,〜也可能区分此场景的特征。
We show that the excess in electron recoil events seen by the XENON1T experiment can be explained by relatively low-mass Luminous Dark Matter candidate. The dark matter scatters inelastically in the detector (or the surrounding rock), to produce a heavier dark state with a ~2.75 keV mass splitting. This heavier state then decays within the detector, producing a peak in the electron recoil spectrum which is a good fit to the observed excess. We comment on the ability of future direct detection datasets to differentiate this model from other Beyond the Standard Model scenarios, and from possible tritium backgrounds, including the use of diurnal modulation, multi-channel signals etc.,~as possible distinguishing features of this scenario.
