论文摘要
我们的月亮是限制暗物质的天然巨型直接检测目标。通过考虑月球的暗物质捕获速率，我们使用背景中微子数据获得了核子上暗物质颗粒的旋转弹性散射横截面的一些约束。 $σ_p^{\ rm si} $的上限可以限制为$ \ sim 10^{ - 38} -10^{ - 36} $ cm $^2 $，对于某些ressonance暗物质质量'范围。这些严格的天体物理约束与直接检测实验获得的约束相辅相成。
Our Moon is a natural giant direct-detection target for constraining dark matter. By considering the dark matter capture rate of the Moon, we obtain some constraints of the spin-independent elastic scattering cross section of dark matter particles on nucleons $σ_p^{\rm SI}$ using the background neutrino data. The upper limits of $σ_p^{\rm SI}$ can be constrained to $\sim 10^{-38}-10^{-36}$ cm$^2$ for certain `resonance dark matter mass' ranges. These stringent astrophysical constraints are complementary to the constraints obtained by the direct-detection experiments.
