We analyze the prospects of reconstructing the mass of a heavy charged Higgsboson %have been analyzed in the context of a Type X two-Higgs doublet modelwhere a light pseudoscalar $A$ in the mass range $40-60$ GeV isphenomenologically allowed, and is in fact favoured if one wants to explain themuon anomalous magnetic moment. The associated production of charged Higgs withthe pseudoscalar $A$ and subsequent decay of the charged Higgs into a $W$ and$A$, is found to be our relevant channel. The branching ratio for $H^+ \to W^+A$ with $M_{H^+} \sim 200$ GeV, is close to 50\%. The hadronic decay of the $W$boson, coupled with the leptonic decays of $A$ into a tau and muon pair, helpin identifying the charged Higgs. The neutral heavy Higgs, being degeneratewith the charged Higgs for most of the allowed parameter space of the model,also contributes to similar final states. Thus both of these particles arereconstructed within a band of about 10 GeV.
