| contents | We study the phenomenology of the charged Higgs boson at future muon colliders. We investigate both the pair production $μ^+ μ^- \to H^+ H^-$, the single production $μ^+ μ^- \to W^\pm H^\mp$, as well as the Vector Boson Fusion (VBF) $\{e^+e^-, μ^+ μ^-\} \to ν\barν H^+ H^-$. We show that the neutral Higgs exchange diagrams in the muon collider case can lead to a significant boost in the cross sections through their Yukawa couplings. Our results for the muon collider are systematically compared to the corresponding ones at $e^+e^-$ machines. It is demonstrated that the vector boson fusion (VBF) $e^+e^- \to ν\barν H^+ H^-$ can compete with the mentioned $2\to 2$ processes. We select benchmark points and perform signal-background analyses, taking into account detector simulations. We demonstrate the discovery region at $5σ$ and the excluded region at $2σ$ levels at a 3 TeV muon collider. |
