Summary: In light of the recent discovery of a neutral Higgs boson, \(H_{\mathrm{obs}}\), with a mass near 125 GeV, we reassess the LHC discovery potential of a charged Higgs boson, \(H^{\pm}\), in the \(W^{\pm}H_{\mathrm{obs}}\) decay channel. This decay channel can be particularly important for a \(H^{\pm}\) heavier than the top quark, when it is produced through the \(pp\to t\,H^{\pm}\) process. The knowledge of the mass of \(H_{\mathrm{obs}}\) provides an additional handle in the kinematic selection when reconstructing a Breit-Wigner resonance in the \(H_{\mathrm{obs}}\to b\bar{b}\) decay channel. We consider some extensions of the Standard Model Higgs sector, with and without supersymmetry, and perform a dedicated signal-to-background analysis to test the scope of this channel for the LHC running at the design energy (14 TeV), for 300 fb\(^{-1}\) (standard) and 3000 fb\(^{-1}\) (high) integrated luminosities. We find that, while this channel does not show much promise for a supersymmetric \(H^{\pm}\) state, significant portions of the parameter spaces of several two-Higgs doublet models are testable.
