Description

We study the phenomenology of the charged Higgs boson at future muon colliders. We investigate both 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−} → ννH¯+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− → ννH¯+H− can compete with the mentioned 2 → 2 processes. We select benchmark points and perform signal-background analyses, considering detector simulations. We demonstrate the discovery region at 5σ and the excluded region at 2σ levels at a 3 TeV muon collider.
