论文摘要
我们提出了一个腐烂的冷暗物质模型,以解释在Xenon1t实验中观察到的电子后坐力的过量。在这种情况下,父母的暗物质很容易获得足够大的速度,足以使电子后坐力能量的峰值饱和2.5 keV,并且可以通过父母的深色物质来实现观察到的信号速率,而10-200 MEV的订单和比宇宙年龄更大的寿命可以实现。我们验证该模型与暗物质检测,宇宙微波背景和大规模结构实验的实验极限一致。
We propose a decaying cold dark matter model to explain the excess of electron recoil observed at the XENON1T experiment. In this scenario, the daughter dark matter from the parent dark matter decay easily obtains velocity large enough to saturate the peak of the electron recoil energy around 2.5 keV, and the observed signal rate can be fulfilled by the parent dark matter with a mass of order 10-200 MeV and a lifetime larger than the age of Universe. We verify that this model is consistent with experimental limits from dark matter detections, Cosmic Microwave Background and Large Scale Structure experiments.
