三维WIMP-核弹性散射事例的Monte Carlo逐散射模拟

Monte Carlo Scattering-by-Scattering Simulation of 3-Dimensional Elastic WIMP-Nucleus Scattering Events

Chung-Lin Shan

摘要:

本文作为我们第三步研究的第一部分,即发展利用定向直接暗物质探测实验提供的三维信息的数据分析程序,我们提出了我们的双蒙特卡罗“散射-散射”三维弹性WIMP-核散射过程的模拟,它可以提供三维速度信息在不同天体坐标系中,每个入射晕WIMP的大小、方向和入射/散射时间,以及散射靶核的反冲方向和反冲能量。为方便读者参考,可在我们的在线(交互式)演示网页(http://www.tir.tw/phys/hep/dm/amidas-2d/)上找到并下载具有不同WIMP质量的(动画)模拟图和所有可运行地下实验室的几种常用靶核。

英文摘要:

In this paper, as the first 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 present our double-Monte Carlo "scattering-by-scattering" simulation of the 3-dimensional elastic WIMP-nucleus scattering process, which can provide 3-D velocity information (the magnitude, the direction, and the incoming/scattering time) of each incident halo WIMP as well as the recoil direction and the recoil energy of the scattered target nucleus in different celestial coordinate systems. For readers' reference, (animated) simulation plots with different WIMP masses and several frequently used target nuclei for all functionable underground laboratories can be found and downloaded on our online (interactive) demonstration webpage (http://www.tir.tw/phys/hep/dm/amidas-2d/).
