| contents | We investigate the phenomenology of the charged Higgs boson within the Two-Higgs-Doublet Type-II Seesaw Model (2HDMcT Type-III) at future $μ^+ μ^-$ colliders. Focusing on $2 \to 2$ processes such as $μ^+ μ^- \to H^+_1 S^-$ ($S^- = H^-_1, H^-_2$) and $μ^+ μ^- \to H^+_1 W^-$, we incorporate both theoretical and experimental constraints to assess their production prospects. We find that $σ(μ^+ μ^- \to H_1^+ H_1^-)$ can reach or exceed the corresponding $e^+ e^-$ cross section, while $σ(μ^+ μ^- \to H_1^+ H_2^-)$ is roughly eighteen times smaller but can be enhanced up to 0.62 fb upon relaxing electroweak precision observables constraints. Moreover, we observe that the cross section for $μ^+ μ^- \to H^+_1 W^-$ is significantly enhanced due to the large $\tanβ$ amplification characteristic of the Type-III scenario. Furthermore, we conduct a signal-background analysis and determine the discovery ($5σ$) regions at a 3 TeV muon collider for the $μ^+ μ^- \to H_1^+ H_1^-$, $μ^+ μ^- \to H_1^+ H_2^-$, and $μ^+ μ^- \to W^\pm H_1^\mp$ processes. |
