Charged Higgs Prospects In Extended Gauge Models

Abstract

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 $W^{{}^{\prime }}Z/W{Z}^{{}^{\prime }}$ channels. We formulate a search strategy for the $H^{\pm }$ in the channel $\sigma (gb\to H^{\pm }t)\mathcal{B}\mathcal{R}(H^{\pm }\to W^{\prime }Z)$ considering the interesting cascade decay chain $H^{\pm }\to W^{{}^{\prime }}Z\to W^{\pm }ZZ$. 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 ($\mathcal{L}=1000f{b}^{-1}$ and above) can probe.
