Description
We study the phenomenology of the charged Higgs boson at future muon colliders. We investigate the pair production μ+μ-→H+H-, the single production μ+μ-→W±H∓, as well as the vector boson fusion (VBF) {e+e-,μ+μ-}→νν¯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 VBF e+e-→νν¯H+H- can compete with the mentioned 2→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.
