论文摘要
在这封信中，我们表明量子重力导致暗物质候选者群体的下限和上限。这些界限取决于候选暗物质的旋转以及暗物质部门相互作用的性质。例如，对于Singlet标量暗物质，我们发现质量范围$ 10^{ - 3} {\ rm ev} \ sillssim m_ϕ \ silysim 10^{7} {\ rm ev} $。下限来自第五力类型相互作用的限制，以及来自暗物质候选者的寿命的上限。
In this letter, we show that quantum gravity leads to lower and upper bounds on the masses of dark matter candidates. These bounds depend on the spins of the dark matter candidates and the nature of interactions in the dark matter sector. For example, for singlet scalar dark matter, we find a mass range $10^{-3}{\rm eV} \lesssim m_ϕ\lesssim 10^{7}{\rm eV}$. The lower bound comes from limits on fifth force type interactions and the upper bound from the lifetime of the dark matter candidate.
