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 $$W^{'}Z/ WZ^{'}$$ W ′ Z / W Z ′ channels. W...

| Summary: | 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 $$W^{'}Z/ WZ^{'}$$ W ′ Z / W Z ′ channels. We formulate a search strategy for the $$H^{\pm }$$ H ± in the channel $$\sigma (g b \rightarrow H^{\pm }t){\mathcal{B}\mathcal{R}}(H^{\pm } \rightarrow W' Z)$$ σ ( g b → H ± t ) B R ( H ± → W ′ Z ) considering the interesting cascade decay chain $$H^{\pm } \rightarrow W^{'} Z \rightarrow W^{\pm } Z Z$$ H ± → W ′ Z → W ± 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 ( $${\mathcal {L}} = 1000~\text {fb}^{-1}$$ L = 1000 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 $$H^{\pm }$$ H ± as well as in a more realistic electroweak symmetry breaking scenario. |
