论文摘要

一方面,两个WIMP暗物质(DM)组件的识别和隔离是广泛的兴趣,但另一方面极具挑战性,尤其是当两个DM组件的主要信号均为单X型($ x =γ,z,h $)时。在强调$ e^+e^ - $ collider更适合此目标之后,我们首先确定在双DM场景中控制两个缺失能量(ME)分布中两个峰的理论原理。然后,我们确定一个相当壮观地引起双峰行为的变量,即对我的统计意义($ s/\ sqrt {b} $)的图。使用直方图的高斯拟合,我们应用了一组由我们制定的标准,以在数值上说明适合基准的数值点。

The identification and isolation of two WIMP dark matter (DM) components at colliders is of wide interest on the one hand but extremely challenging on the other, especially when the dominant signal of both DM components is of the mono-X type ($X=γ, Z, H$). After emphasizing that an $e^+e^-$ collider is more suitable for this goal, we first identify the theoretical principles that govern the occurrence of two peaks in missing energy (ME) distribution, in a double-DM scenario. We then identify a variable that rather spectacularly elicits the double-peaking behaviour, namely, the plot of bin-wise statistical significance ($S/\sqrt{B}$) against ME. Using Gaussian fits of the histograms, we apply a set of criteria developed by us, to illustrate the above points numerically for suitable benchmarks.
