摘要： 暗物质（DM）的性质，据认为构成宇宙的四分之一，仍然是一个谜。 有证据表明，大部分DM可能由尚未发现的粒子组成，全球有多个实验正在尝试检测这些粒子。 在本文中，我们介绍了一些新的候选者，它们的性质较为奇特，但仍与已知物理规律一致。 我们研究了通过引力与四费米子力、核张力等平衡形成的DM天体。 我们发现它们的半径远大于其对应的施瓦茨希尔德半径；因此，它们与霍金原初黑洞不同。 我们已经确定了它们的质量以及用于解释银河系中DM的必要数密度，并探讨了探测它们的可能方法。 显示英文摘要

摘要： The nature of dark matter (DM), which is supposed to constitute about one-fourth of the universe, is still a mystery. There is evidence that much of the DM may be made up of as yet undiscovered particles with several experiments all over the world trying to detect these. In this article we introduce some new candidates which are exotic in nature but still are consistent with known physics. We look at DM objects that can be formed by the balance of gravity with the four-fermion force, nuclear tension, etc. We see that their radii are much larger than their corresponding Schwarzschild radius; hence they are distinct from Hawking primordial black holes. We have determined their mass and the required number densities to account for the DM in the galaxy and possible ways of detecting them.
