论文摘要
在树级别上的$ h^\ pm w^\ mp z $相互作用是具有标量三重态的新物理模型的常见功能。在这项研究中，我们旨在以未来派的27 TEV Proton-Proton碰撞器以模型不稳定的方式探测上述相互作用的强度。我们假设$ h^\ pm $ couples主要到（$ w^\ pm，z $）和（$ t，b $）。我们专门研究了涉及$ h^\ pm w^\ mp z $顶点的过程，即$ p p \ to h^\ pm j j $和$ p p \ to z h^\ pm $。此外，我们将两个$ h^\ pm \ to to w^\ pm z，〜t b $衰减的任何一种生产过程。我们的调查表明，与$ z h^\ pm $相比，$ h^\ pm j j $生产过程具有更大的影响力。此外，相对于对应于较低质量中心能量的早期研究，带电的希格斯的发现潜力显着提高。最后，我们在流行的Georgi-Machacek模型的背景下重新铸造了结果。
An $H^\pm W^\mp Z$ interaction at the tree level is common feature of new physics models that feature scalar triplets. In this study, we aim to probe the strength of the aforementioned interaction in a model-agnostic fashion at the futuristic 27 TeV proton-proton collider. We assume that the $H^\pm$ couples dominantly to ($W^\pm,Z$) and ($t,b$). We specifically study the processes that involve the $H^\pm W^\mp Z$ vertex at the production level, that is, $p p \to H^\pm j j$ and $p p \to Z H^\pm$. Moreover, we look into both $H^\pm \to W^\pm Z,~t b$ decays for either production process. Our investigations reveal that the $H^\pm j j$ production process has a greater reach compared to $Z H^\pm$. Moreover, the discovery potential of a charged Higgs improves markedly with respect to the earlier studies corresponding to lower centre-of-mass energies. Finally, we recast our results in the context of the popular Georgi-Machacek model.
