With the standard model working well in describing the collider data, the focus is now on determining the standard model parameters as well as for any hint of deviation. In particular, the determination of the couplings of the Higgs boson with itself and with other particles of the model is important to better understand the electroweak symmetry breaking sector of the model. In this letter, we look at the process $pp\to WWH$, in particular through the fusion of bottom quarks. Due to the non-negligible coupling of the Higgs boson with the bottom quarks, there is a dependence on the $WWHH$ coupling in this process. This sub-process receives the largest contribution when the W bosons are longitudinally polarized. We compute one-loop QCD corrections to various final states with polarized W bosons. We find that the corrections to the final state with the longitudinally polarized W bosons are large. It is shown that the measurement of the polarization of the W bosons can be used as a tool to probe the $WWHH$ coupling in this process. We also examine the effect of varying $WWHH$ coupling in the κ-framework.

由于标准模型在描述对撞机数据方面运行良好，现在的重点是确定标准模型参数以及任何偏差迹象。特别是，确定希格斯玻色子与其自身以及模型的其他粒子的耦合对于更好地理解模型的电弱对称破坏扇区很重要。在这封信中，我们来看看这个过程$磷磷\to 宽宽H$，特别是通过底夸克的融合。由于希格斯玻色子与底夸克的不可忽略的耦合，存在依赖于$宽宽HH$在这个过程中耦合。当W玻色子被纵向极化时，这个子过程得到最大的贡献。我们使用极化的W玻色子计算对各种最终状态的单环 QCD 校正。我们发现纵向极化的W玻色子对最终状态的修正很大。结果表明，W玻色子极化的测量可以作为探测粒子的工具。$宽宽HH$在这个过程中耦合。我们还检查了不同的影响$宽宽HH$κ框架中的耦合。
