我们重温了直接探测实验中的发光暗物质的探测。在这种情况下，暗物质吸热散射产生激发态，激发态衰变产生光子。我们探索的方法，从衰变光子的电子反冲信号可以区分从其他潜在的电子反冲信号具有狭窄的光谱形状。我们发现，更大的体积/曝光氙探测器将无法区分信号的起源，没有显着改善探测器的能量分辨率约一个数量级。我们还探讨了什么可以了解一个通用的发光暗物质信号与更高分辨率的探测器。由于固态探测器能量分辨率的进步，我们发现亚电子伏特的分辨率使得在存在背景能级的情况下发现LDM成为可能，否则观测是不可能的。我们还发现，亚电子伏特的分辨率可以用来确定的形状的发光暗物质衰变谱，从而约束暗物质的质量和速度分布。
We revisit the detection of luminous dark matter in direct detection experiments. In this scenario, dark matter scatters endothermically to produce an excited state, which decays to produce a photon. We explore ways in which the electron recoil signal from the decay photon can be differentiated from other potential electron recoil signals with a narrow spectral shape. We find that larger volume/exposure xenon detectors will be unable to differentiate the signal origin without significant improvements in detector energy resolution of around an order of magnitude. We also explore what can be learned about a generic luminous dark matter signal with a higher resolution detector. Motivated by the advancements in energy resolution by solid-state detectors, we find that sub-eV resolution enables the discovery of LDM in the presence of background levels that would otherwise make observation impossible. We also find that sub-eV resolution can be used to determine the shape of the luminous dark matter decay spectrum and thus constrain the dark matter mass and velocity distribution.
