暗物质质量的理论界限

Theoretical bounds on dark matter masses

Xavier Calmet, Folkert Kuipers

摘要:

在这封信中,我们表明量子引力导致暗物质候选者的质量上下限。这些界限取决于暗物质候选者的自旋和暗物质扇区中相互作用的性质。例如,对于单重标量暗物质,我们发现质量范围为$10^{-3}{\rm eV} \lesssim m_ϕ\lesssim 10^{7}{\rm eV}$。下限来自第五种力类型相互作用的限制,上限来自暗物质候选者的寿命。

英文摘要:

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.
