使用ISR的模型无关WIMP表征
Model-independent WIMP Characterisation using ISR
摘要：
探讨了在国际直线对撞机上用模型无关的方法测量WIMP暗物质参数的前景。所研究的信号是直接产生的WIMP对与相关的初始状态辐射。在ILD探测器概念的完全模拟中进行分析。利用L = 500 fb-1的积分亮度和真实的束流偏振，可以确定WIMP与电子耦合的螺旋度结构，并可以测量质量和截面到百分比水平。系统不确定度主要由偏振测量和光度谱决定。
英文摘要：
The prospects of measuring the parameters of WIMP dark matter in a model independent way at the International Linear Collider are investigated. The signal under study is direct WIMP pair production with associated initial state radiation. The analysis is performed in full simulation of the ILD detector concept. With an integrated luminosity of L = 500 fb-1 and realistic beam polarizations the helicity structure of the WIMP couplings to electrons can be determined, and the masses and cross sections can be measured to the percent level. The systematic uncertainties are dominated by the polarization measurement and the luminosity spectrum.
