定向暗物质探测实验中WIMP散射靶核角能分布的模拟

Simulations of the Angular Recoil-Energy Distribution of WIMP-Scattered Target Nuclei for Directional Dark Matter Detection Experiments

Chung-Lin Shan

摘要:

本文作为第三步研究的第二部分,研究了在不同天体坐标系下观测到的WIMP散射靶核的反冲方向(通量)和反冲能量的角分布,为将来利用定向直接暗物质探测实验提供的三维信息开发数据分析程序提供了依据。将演示角反冲方向/能量分布的“各向异性”和“方向性”(“年度”调制)。我们还将讨论它们对靶核和入射晕WIMP质量的依赖性。为方便读者参考,本文中介绍的所有模拟图(以及更多)都可以在我们的在线(交互式)演示网页(http://www.tir.tw/phys/hep/dm/amidas-2d/)上找到“动画”。

英文摘要:

In this paper, as the second part of the third step of our study on developing data analysis procedures for using 3-dimensional information offered by directional direct Dark Matter detection experiments in the future, we investigate the angular distributions of the recoil direction (flux) and the recoil energy of the Monte Carlo simulated WIMP-scattered target nuclei observed in different celestial coordinate systems. The "anisotropy" and the "directionality" ("annual" modulation) of the angular recoil-direction/energy distributions will be demonstrated. We will also discuss their dependences on the target nucleus and on the mass of incident halo WIMPs. For readers' reference, all simulation plots presented in this paper (and more) can be found "in animation" on our online (interactive) demonstration webpage (http://www.tir.tw/phys/hep/dm/amidas-2d/).
