直接探测实验中残留背景事件对WIMP暗物质识别的影响

Effects of Residue Background Events in Direct Detection Experiments on Identifying WIMP Dark Matter

Chung-Lin Shan

摘要:

我们重新检查的模型独立的数据分析方法提取的弱相互作用大质量粒子(WIMP)的属性,直接使用数据(测量反冲能量)从直接的暗物质探测实验,作为一个更现实的研究,考虑一小部分残留的背景事件,通过所有的歧视标准,然后与其他真正的WIMP诱导的信号在分析的数据集中。在这次演讲中,将讨论剩余背景对确定WIMP质量的影响以及核子上自旋无关的WIMP耦合。

英文摘要:

We reexamine the model-independent data analysis methods for extracting properties of Weakly Interacting Massive Particles (WIMPs) by using data (measured recoil energies) from direct Dark Matter detection experiments directly and, as a more realistic study, consider a small fraction of residue background events, which pass all discrimination criteria and then mix with other real WIMP-induced signals in the analyzed data sets. In this talk, the effects of residue backgrounds on the determination of the WIMP mass as well as the spin-independent WIMP coupling on nucleons will be discussed.
