用发光暗物质解释XENON1T过剩

Explaining the XENON1T excess with Luminous Dark Matter

Nicole F. Bell, James B. Dent, Bhaskar Dutta, Sumit Ghosh, Jason Kumar, Jayden L. Newstead

摘要:

我们表明,在XENON 1 T实验中看到的电子反冲事件的过剩可以解释相对低质量的发光暗物质候选人。暗物质在探测器(或周围的岩石)中非弹性地散射,以产生具有~2.75 keV质量分裂的更重的暗态。然后,这个较重的状态在探测器内衰变,在电子反冲光谱中产生一个峰值,这与观察到的过量非常吻合。我们评论了未来直接探测数据集将该模型与其他超越标准模型的场景区分开来的能力,以及与可能的氚背景区分开来的能力,包括使用昼夜调制,多通道信号等。作为这个场景的可能的区别特征。

英文摘要:

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.
