论文摘要

我们试图通过Dama -libra数据的季节变化来解释对暗物质的观察,以及对Xenon1t的“电子后坐力”事件的观察,其中液体XE闪烁体受到电子的激发 - 在预期的背景中 - 通过相同的暗物质模型。在我们的模型中,暗物质由含有普通原子质的新型真空的气泡组成,例如,在高压下,通过分离域壁的表面张力确保了钻石。我们还试图解释矮星系天文学研究和星系簇的中心结构所暗示的暗物质的自我相互作用。与屏蔽中物质的相互作用负责将暗物质减慢至低末端速度,因此地下探测器的检测能量不足。此外,我们解释了3.5 keV的“神秘” X射线线,甚至是Tycho Supernova Remnant的3.5 KEV X射线辐射。 Dama-Libra和Xenon1t实验可见腐烂的暗物质珍珠。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。如在矮星系研究中所观察到的暗物质的自我相互作用,我们以数值方式将横截面拟合,并发现珍珠的尺寸与我们模型中最小的可能性相当接近。但是,达玛会导致一些问题获得较重的珍珠。同样,暗物质珍珠在盾牌中停止的总能量是合理匹配的。接受真空的不同阶段,该模型可以在标准模型中实现,我们的整个方案可以在标准模型中实现。

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.
