Light charged Higgs scalars at high-energy e+e− colliders Original Research Article

We study the prospects for detecting light charged Higgs scalars (H±) at future e+e− colliders. Various two-Higgs-doublet models (2HDM) and a general multi-Higgs-doublet model (MHDM) are considered, all of which may contain a H± in the discovery range of LEP2. The potentially troublesome cases of MH± ∼ MW and MH± ∼ MZ are discussed, as well as ways of distinguishing the different models.
