Charged Higgs prospects in extended gauge models

Abstract

In this paper, we explore the collider phenomenology of charged Higgs bosons 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 sigma (g b rightarrow H^{pm }t){mathcal{B}mathcal{R}}(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~text {fb}^{-1} and above) can probe. We then study the phenomenological implications of our findings in the context of a generic toy model with a H^{pm } as well as in a more realistic electroweak symmetry breaking scenario.
