通过单次直接检测实验确定WIMP质量

Determining the WIMP mass from a single direct detection experiment

Anne M Green

摘要:

在弱相互作用大质量粒子(WIMP)直接探测实验中,核反冲能谱依赖于WIMP的质量(轻WIMP质量依赖性强,重WIMP质量依赖性弱)。我们讨论了如何与WIMP质量的准确性可以确定由一个单一的直接检测实验依赖于检测器的配置和WIMP的属性。特别是,我们研究了不同的基础WIMP质量,探测器目标核,曝光,能量阈值和最大能量,局部速度分布和背景事件率和频谱的影响。

英文摘要:

The energy spectrum of nuclear recoils in Weakly Interacting Massive Particle (WIMP) direct detection experiments depends on the underlying WIMP mass (strongly for light WIMPs, weakly for heavy WIMPs). We discuss how the accuracy with which the WIMP mass could be determined by a single direct detection experiment depends on the detector configuration and the WIMP properties. In particular we examine the effects of varying the underlying WIMP mass, the detector target nucleus, exposure, energy threshold and maximum energy, the local velocity distribution and the background event rate and spectrum.
