论文摘要
在本文中，作为我们关于WIMP裂片靶核的后坐力通量的角度分布的扩展，我们证明了通过使用或组合与方向核中不同靶核的“脊丝网”结构的“山脊 - 扭伤”结构在方向直接直接直接深色物质实验中确定的可能性，可以通过使用或组合“脊界”结构或结合“脊丝网”结构的质量。我们的仿真结果表明，对于仅几十个GEV的w骨质量，光和重靶核的立体角升压分布将具有（纵向）“脊样”结构。然而，一旦w斑块像几百个GEV一样沉重，重量靶核的角度后升 - 升华分布将显示出（纬度）“陨石坑样”结构。
In this article, as an extension of our study on the angular distribution of the recoil flux of WIMP-scattered target nuclei, we demonstrate a possibility of determining the mass of incident halo WIMPs by using or combining "ridge-crater" structures of the angular recoil-energy spectra with different target nuclei observed in directional direct Dark Matter detection experiments. Our simulation results show that, for a WIMP mass of only a few tens GeV, the stereoscopic angular recoil-flux distributions of both of light and heavy target nuclei would have a (longitudinally) "ridge-like" structure. However, once the WIMP mass is as heavy as a few hundreds GeV, the angular recoil-flux distributions of heavy target nuclei would in contrast show a (latitudinally) "crater-like" structure.
