Charged Higgs prospects in extended gauge models

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^± in the channel σ(gb→ H^±t) BR(H^±→ W^′Z) considering the interesting cascade decay chain H±→W′Z→W±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 (L=1000fb-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^± as well as in a more realistic electroweak symmetry breaking scenario.
