Singly charged Higgs scalars at linear collider

Abstract We consider the production of singly charged Higgs bosons in the Higgs triplet and two Higgs doublet models. We evaluate the cross sections for the pair production and the single production of charged Higgs bosons at linear collider. The decay modes of H + and the Standard Model backgrounds are considered. We analyze the possibilities to differentiate between the triplet and two Higgs doublet models.
