Observability of Parameter Space for Charged Higgs Boson in its bosonic decays in Two Higgs Doublet Model Type-1

This study explores the possibility of discovering $H^{\pm }$ through its bosonic decays, i.e. $H^{\pm }\to W^{\pm }\phi$ (where $\phi$ = h or A), within the Type-I Two Higgs Doublet Model (2HDM). The main objective is to demonstrate the available parameter space after applying the recent experimental and theoretical exclusion limits. We suggest that for $m_{H^{\pm }}$ = 150 GeV is the most probable mass for the $H^{\pm }\to W^{\pm }\phi$ decay channel in $pp$ collisions at $\sqrt{s}$ = 8, 13 and 14 TeV. Therefore we propose that this channel may be used as an alternative to $H^{\pm }\to {\tau }^{\pm }\nu$.
