论文摘要
在我们较早地完成了银河wimp的三维有效速度分布（不仅撞击我们的探测器，而且还撞击了目标核），我们在本文中散射了靶核，我们证明了弹性的WIMP核核散射的正常和“反向”调节，这在直接的暗物质检测实验中可以观察到。我们的模拟表明，一旦WIMP质量像几十亿GEV一样轻，事件数和WIMP诱导的散射事件的累积后坐力在夏季（冬季）确实将是最大的（最小）（冬季）。但是，一旦w污质量像几百个GEV一样重，事件数和wimp散射事件的累积后坐力在夏季将呈现为最小。可以理解的是，对于中间的w骨质量，事件数和一些中间质量核的散射事件的累积后坐力将显示出大约均匀的时间依赖性。
Following our earlier work on the 3-dimensional effective velocity distribution of Galactic WIMPs (not only impinging on our detectors but also) scattering off target nuclei, in this paper, we demonstrate the normal and a "reverse" annual modulations of elastic WIMP-nucleus scattering signals, which could be observed in direct Dark Matter detection experiments. Our simulations show that, once the WIMP mass is as light as only a few tens GeV, the event number and the accumulated recoil energy of WIMP-induced scattering events off both of light and heavy target nuclei would indeed be maximal (minimal) in summer (winter). However, once the WIMP mass is as heavy as a few hundreds GeV, the event number and the accumulated recoil energy of WIMP scattering events off heavy nuclei would inversely be minimal in summer. Understandably, for an intermediate WIMP mass, the event number and the accumulated recoil energy of scattering events off some middle-mass nuclei would show an approximately uniform time dependence.
