Title: Search for the light charged Higgs boson in the Type-I Two-Higgs-Doublet Model

Abstract: This talk explores the search for light charged Higgs boson $H^{\pm }$ in the Type-I Two-Higgs-Doublet Model, focusing on masses below the top quark mass. We explore the parameter space which satisfies the theoretical constraints and current experimental constraints. We find that the pseudoscalar mass $M_A$ is a crucial factor for the phenomenology of the charged Higgs bosons. Over the entire viable parameter space, we study all possible production and decay modes of charged Higgs boson at the LHC and suggest three efficient channels: 
(i) $pp\to H^{+}{H}^{-}\to [\tau \nu ][\tau \nu ]$, (ii) $pp\to HA/HH/AA\to H^{\pm }{W}^{\mp }{H}^{\pm }{W}^{\mp }\to [\tau \nu ][\tau \nu ]WW$, and (iii) $pp\to H^{+}{H}^{-}\to [bbW][bbW]$. 
We also study the charged Higgs decay into an off-shell top and b quark for $H^{\pm }$ masses between 130 and 170 GeV. We investigate the discovery potential of future colliders, HL-LHC and Muon Collider for this off-shell decay mode.
