论文摘要
矢量玻色子散射是众所周知的电动对称性破裂的探针。在这里，我们研究了两个Electroweak Vector Boson的相关过程，这些过程散射到矢量玻色子和Higgs Boson中（$ VV \ Rightarrow VH，V = W，Z $）。如果希格斯耦合到电子玻色子偏离其标准模型值，则该过程表现出树级干扰并随着能量而生长。因此，此过程对希格斯与$ w $和$ z $，$λ_{wz} $之间耦合比率的相对符号特别敏感。在这项工作中，我们表明，高能量Lepton对撞机非常适合通过向量玻色融合来研究此过程，估计对该比率的潜在敏感性，并表明相对适量的数据可以排除$λ_{wz} \ simeq -1 $。
Vector boson scattering is a well known probe of electroweak symmetry breaking. Here we study a related process of two electroweak vector bosons scattering into a vector boson and a Higgs boson ($VV \rightarrow Vh, V=W,Z$). This process exhibits tree level interference and grows with energy if the Higgs couplings to electroweak bosons deviate from their Standard Model values. Therefore, this process is particularly sensitive to the relative sign of the ratio of the coupling between the Higgs and the $W$ and $Z$, $λ_{WZ}$. In this work we show that a high energy lepton collider is well suited to study this process through vector boson fusion, estimate the potential sensitivity to this ratio, and show that a relatively modest amount of data can exclude $λ_{WZ} \simeq -1$.
