Description
In this talk, we explore the collider phenomenology of the charged Higgs boson in the context of a Beyond Standard Model scenario with extended gauge and scalar sector. Because of the intricate pattern of symmetry breaking, the charged Higgs can simultaneously decay via heavy gauge boson mediated channels ($W^{'}Z/ WZ^{'}$) along with the traditional SM decay modes. Our goal here is to formulate the search strategy of the $H^{\pm}$ in the channel $\sigma(g b \rightarrow H^{\pm}t)\mathcal{BR}(H^{\pm} \rightarrow W^{'} Z)$. Since the $W^{'}_{\mu}$ boson in this model does not couple to SM fermions in tree level, it opens up interesting cascade decay chain: $H^{\pm} \rightarrow W^{'} Z \rightarrow W^{\pm} Z Z$. As a result the charged Higgs can be discovered in the final state with multiple hard leptons and/ or b-quarks which future LHC experiments with sufficiently large luminosity (say, $\mathcal{L} = 1000 fb^{-1}$) can probe.
