原子大小的珍珠是发出电子信号的暗物质

Atomic Size Pearls being Dark Matter giving Electron Signal

C. D. Froggatt, H. B. Nielsen

摘要:

我们试图通过DAMA-LIBRA数据的季节性变化来解释暗物质的表面观测,以及通过相同的暗物质模型来解释氙1 T的“电子反冲”事件的观测,在氙1 T中,液体闪烁体被电子激发-超过预期的背景。在我们的模型中,暗物质是由一种新型的真空泡组成的,这种真空泡中含有普通的原子物质,比如金刚石,处于分离畴壁的表面张力所确保的高压之下。我们还试图解释天文学研究矮星系和星系团的中心结构所提出的暗物质的自相互作用。与屏蔽层中物质的相互作用是暗物质减速到低终极速度的原因,因此地下探测器没有足够的能量进行探测。此外,我们解释了“神秘的”3.5 keV的X射线线,甚至3.5 keV的X射线辐射从第谷超新星遗迹。DAMA-LIBRA和Xenon 1 T实验看到了腐烂的暗物质珍珠。这两个地下实验都看到了大约3.5 keV能量的事件,只是X射线线的能量。我们数值拟合的横截面与质量比的暗物质的自相互作用的研究中观察到的矮星系,并发现珍珠的大小是相当接近的最小可能在我们的模型。然而,DAMA导致一些问题,以获得更重的珍珠。而且,阻挡在防护罩中的暗物质珍珠的总能量也是合理匹配的。接受真空的不同阶段,该模型可以在标准模型内实现,我们的整个方案可以在标准模型内实现。

英文摘要:

We seek to explain both the seeming observation of dark matter by the seasonal variation of the DAMA-LIBRA data and the observation of "electron recoil" events at Xenon1T in which the liquid Xe scintillator was excited by electrons - in excess to the expected background - by the same dark matter model. In our model the dark matter consists of bubbles of a new type of vacuum containing ordinary atomic matter, say diamond, under high pressure ensured by the surface tension of the separation domain wall. We also seek to explain the self interactions of dark matter suggested by astronomical studies of dwarf galaxies and the central structure of galaxy clusters. The interaction with matter in the shielding is responsible for slowing the dark matter down to a low terminal velocity, so underground detectors have insufficient energy for detection. Further we explain the "mysterious" X-ray line of 3.5 keV, even the 3.5 keV X-ray radiation from the Tycho supernova remnant. The DAMA-LIBRA and Xenon1T experiments see decaying dark matter pearls. Both these underground experiments see events with about 3.5 keV energy, just the energy of the X-ray line. We fit numerically the cross section over mass ratio for the self interaction of the dark matter as observed in the study of dwarf galaxies and find the size of the pearls to be rather close to the smallest possible in our model. However DAMA cause some problem to get heavier pearls. Also the total energy of the dark matter pearls stopped in the shield is reasonably matching. Accepting the different phases of the vacuum the model could be realized inside the Standard Model, our whole scheme could be realized inside the Standard Model.
