论文摘要
对带电的三重量规耦合（CTGC）的精确知识对于确定HIGGS耦合以及超越标准模型以外的物理学很重要。未来的高能量$ e^{+} e^{ - } $ colliders对异常CTGC的敏感性显着提高。此处介绍的拟合框架与手性横截面和梁极化参数并行提取CTGC。它表明CTGC可以在$ 10^{ - 3} -10^{ - 4} $范围内以精度进行测量。观察到CTGC敏感性对可用的亮度和极化的强烈依赖性。
A precise knowledge of charged Triple Gauge Couplings (cTGCs) is important for the determination of Higgs couplings and for constraining physics beyond the Standard Model. Future high-energy $e^{+}e^{-}$ colliders could have a significantly improved sensitivity to anomalous cTGCs. The fit framework presented here extracts cTGCs in parallel with chiral cross sections and beam polarisation parameters. It demonstrates that cTGCs can be measured with precision in the $10^{-3}-10^{-4}$ range. A strong dependence of the cTGC sensitivity on the available luminosities and polarisations is observed.
