摘要:

在国际直线对撞机(ILC)测量分支分数的$H \to μ^+ μ^-$的前景进行了评估的基础上,考虑到中心的质量能量($\sqrt{s}$)为250 GeV和500 GeV的国际大型探测器(ILD)的概念,一个完整的探测器模拟。对于两种$\sqrt{s}$情况,分析了两种最终状态$e^+ e^- \to q\overline{q}H$和$e^+ e^- \to ν\overlineνH$。对于$\sqrt{s} = 250$ GeV的2 ab $^{-1}$和$\sqrt{s} = 500$ GeV的4 ab $^{-1}$的积分亮度,估计$H \to μ^+ μ^-$的分支分数的组合精度为17{\%}。本文还研究了横向动量分辨率对这一分析的影响。

英文摘要:

The prospects for measuring the branching fraction of $H \to μ^+ μ^-$ at the International Linear Collider (ILC) have been evaluated based on a full detector simulation of the International Large Detector (ILD) concept, considering centre-of-mass energies ($\sqrt{s}$) of 250 GeV and 500 GeV. For both $\sqrt{s}$ cases, the two final states $e^+ e^- \to q\overline{q}H$ and $e^+ e^- \to ν\overlineνH$ have been analyzed. For integrated luminosities of 2 ab$^{-1}$ at $\sqrt{s} = 250$ GeV and 4 ab$^{-1}$ at $\sqrt{s} = 500$ GeV, the combined precision on the branching fraction of $H \to μ^+ μ^-$ is estimated to be 17{\%}. The impact of the transverse momentum resolution for this analysis is also studied.
