论文摘要

作为对Guiot,Borquez,Deur和Werner在“仓库和暗物质”上进行的开创性工作的跟进,我们明确地表明,与爱因斯坦的引力相反,在弦乐理论中,本地和非局部较高衍生的理论以及一般无限制的理论相互作用的能量是更大的能量。另一方面,在较高的衍生或非局部理论中,相互作用由无量纲或尺寸耦合常数控制,当能量小于Planck能量时,结合状态形成。由于紫外线区域中散射幅度的柔软度,因此允许这种结合的状态。确实,在这种理论中,电势是有限的,而力为$ r = 0 $的力为零或恒定。最后,由于早期宇宙中形成的边界状态可能具有从普朗克质量到任何任意大或小价值的能量,因此我们认为它们可以充当候选暗物质候选者和/或作为宇宙中结构大规模形成的种子。

As a follow up of the seminal work by Guiot, Borquez, Deur, and Werner on "Graviballs and Dark Matter", we explicitly show that contrary to Einstein's gravity, in string theory, local and nonlocal higher derivative theories, as well as general asymptotically-free or finite theories, gravitationally interacting bound states can form when the energy is larger than the Planck energy. On the other hand, in higher derivative or nonlocal theories with interaction governed by a dimensionless or a dimensionful coupling constant, the bound states form when the energy is smaller than the Planck energy. Such bound states are allowed because of the softness of the scattering amplitudes in the ultraviolet region. Indeed, in such theories, the potential is finite while the force is zero or constant in $r=0$. Finally, since the bound states that form in the early Universe may have an energy that ranges from the Planck mass to any arbitrarily large or small value, we argue that they can serve as dark matter candidates and/or as the seeds for the structure's formation at large scale in the Cosmos.
