论文摘要
LHC处的PP-> ZZ的外壳HIGGS生产目前提供了在没有超出标准模型贡献的超出标准模型贡献的情况下对HIGGS宽度的最直接测量。在这里，我们分析了异常Z耦合对Higgs宽度测定的影响。我们表明，尽管这些耦合受到可用的Electroweak精确数据的强烈限制，但它们可以在LHC处实质上影响HIGGS的宽度确定2和3。相反，在较大的集成仪性运行中，例如在高亮度LHC和高能LHC设置的高能相互作用的效果，该效果的效果，该效果是在HOM的效果中。
The off-shell Higgs production in pp -> ZZ at LHC provides at present the most direct measurement of the Higgs width in the absence of beyond the standard model contributions. Here, we analyze the impact of anomalous Z couplings to fermions on the Higgs width determination. We show that, despite these couplings being strongly constrained by the available electroweak precision data, they can substantially affect the Higgs width determination at the LHC Runs 2 and 3. Conversely, in larger integrated luminosities runs, such as those foreseen at the high luminosity LHC and high energy LHC setups, the effect of such anomalous interactions in the Higgs width measurement is minimal.
