Preview Abstract
In this paper the charged Higgs signal through triple or double Higgs production in a two Higgs doublet model (2HDM) type II is studied. The main production process is e⁺e^- →H⁺H^-H⁰ followed by the charged Higgs decay to a pair of τν and the neutral Higgs decay to . The alternative process H⁺W^-H⁰ is also included as a source of charged Higgs signal in the analysis. The focus is on a future e⁺e^- linear collider operating at . The final state under consideration is suitable for electroweak background rejection using the b-tagging tools. It is shown that although the signal cross-section is small, with a reasonable background suppression, high signal significance values are achievable at an integrated luminosity 500 fb^-1 depending on the charged Higgs mass, tan β and the CP-odd neutral Higgs mass. Finally results are quoted in terms of the signal significance for charged Higgs in the mass range 160 < m_H^± < 400 GeV.
