Abstract

For the search for additional Higgs bosons in the Minimal Supersymmetric Standard Model (MSSM) as well as for future precision analyses in the Higgs sector precise knowledge of their production properties is mandatory. We evaluate the cross sections for the charged Higgs boson production at $$e^+e^-$$

colliders in the MSSM with complex parameters (cMSSM). The evaluation is based on a full one-loop calculation of the production mechanism $e^+e^- \rightarrow H^+ H^-$ and $e^+e^- \rightarrow H^{\pm } W^{\mp }$ , including soft and hard QED radiation. The dependence of the Higgs boson production cross sections on the relevant cMSSM parameters is analyzed numerically. We find sizable contributions to many cross sections. They are, depending on the production channel, roughly of 5–10 % of the tree-level results, but can go up to 20 % or higher. The full one-loop contributions are important for a future linear $$e^+e^-$$

collider such as the ILC or CLIC.
