论文摘要
在本文中，我们调查了在未来的紧凑型线性碰撞器（CLIC）和350 GEV和3个TEV质量质量能量的未来的$ Z $玻色子中测量标准模型Higgs玻色子衰减的分支分数的前景。考虑到所有相关物理和梁诱导的背景过程，使用对CLIC的检测器进行详细模拟进行研究。结果表明，可以在使用半含量的350 GEV（3 tev（3 tev）的情况下，使用半含量的最终状态，可以用相对的统计不确定性（3.0％），使用$ abs $^abe $^abe $^abect（3 tev）使用$ a $ abe $^$^um^$^abect（3 tev），可以用半度的最终状态（1 abe $ aby）在1 $ abemiN pum^$^abemite $^abemite $^$^$^$^$ abemity $ abe $ abe $ abe $ abe $ a; （5 ab $^{ - 1} $）。
In this paper we investigate the prospects for measuring the branching fraction of the Standard Model Higgs boson decay into a pair of $Z$ bosons at the future Compact Linear Collider (CLIC) at 350 GeV and 3 TeV centre-of-mass energies. Studies are performed using a detailed simulation of the detector for CLIC, taking into consideration all relevant physics and beam-induced background processes. It is shown that the product of the Higgs production cross-section and the branching fraction BR(${H\rightarrow\thinspace ZZ^\ast}$) can be measured with a relative statistical uncertainty of 20% (3.0%) at a centre-of-mass energy of 350 GeV (3 TeV) using semileptonic final states, assuming an integrated luminosity of 1 ab$^{-1}$ (5 ab$^{-1}$).
