摘要：

在本文中，我们探讨了带电希格斯玻色子的对撞机现象的背景下，一个通用的超越标准模型的情况下，扩展规范和标量部门。在这种情况下，带电的希格斯玻色子可以通过$W^{'}Z/ WZ^{'}$通道衰变。我们制定了一个搜索策略的$H^{\pm}$的通道$σ(g b \rightarrow H^{\pm}t)\mathcal{BR}(H^{\pm} \rightarrow W' Z)$考虑有趣的级联衰减链$H^{\pm} \rightarrow W^{'} Z \rightarrow W^{\pm} Z Z$。我们发现带电的希格斯粒子可以在具有多个硬轻子和/或b-夸克的终态中被发现，未来的LHC实验具有足够大的光度（$\mathcal{L} = 1000 fb^{-1}$及以上）可以探测到。

英文摘要：

In this paper, we explore the collider phenomenology of the charged Higgs boson in the context of a generic Beyond Standard Model scenario with extended gauge and scalar sectors. In such scenarios, the charged Higgs boson can decay via the $W^{'}Z/ WZ^{'}$ channels. We formulate a search strategy for the $H^{\pm}$ in the channel $σ(g b \rightarrow H^{\pm}t)\mathcal{BR}(H^{\pm} \rightarrow W' Z)$ considering the interesting cascade decay chain $H^{\pm} \rightarrow W^{'} Z \rightarrow W^{\pm} Z Z$. We find that the charged Higgs can be discovered in final states with multiple hard leptons and/ or b-quarks which future LHC experiments with sufficiently large luminosity ($\mathcal{L} = 1000 fb^{-1}$ and above) can probe.
