摘要
We study the phenomenology of the charged Higgs boson at future muon colliders. We investigate both the pair productionμ⁺ μ⁻ → H⁺ H⁻ , the single productionμ⁺ μ⁻ → W^(±) H^(∓) , as well as the Vector Boson Fusion (VBF){e⁺e⁻, μ⁺ μ⁻} → ν ν̄ 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 ate⁺e⁻machines. It is demonstrated that the vector boson fusion (VBF)e⁺e⁻ → ν ν̄ H⁺ H⁻can compete with the mentioned2→ 2processes. We select benchmark points and perform signal-background analyses, taking into account detector simulations. We demonstrate the discovery region at5σand the excluded region at2σlevels at a 3 TeV muon collider.
