For the search for scalar leptons in the minimal supersymmetric standard model (MSSM) as well as for future precision analyses of these particles an accurate knowledge of their production and decay properties is mandatory. We evaluate the cross sections for the slepton 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 mechanisms e + e − →l gslgs including soft and hard photon radiation. The dependence of the slepton production cross sections on the relevant cMSSM parameters is analyzed numerically. We find sizable contributions to many production cross sections. They amount to roughly 15% of the tree-level results but can go up to 40% or higher in extreme cases. Also the dependence on complex parameters of the one-loop corrections for the production of charged sleptons was found non-negligible. The full one-loop contributions are thus crucial for physics analyses at a future linear e + e − collider such as the ILC or CLIC.

For the search for charginos and neutralinos in the Minimal Supersymmetric Standard Model (MSSM) as well as for future precision analyses of these particles an accurate knowledge of their production and decay properties is mandatory. We evaluate the cross sections for the chargino and neutralino 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 mechanisms e + e − →χ ± cχ ∓ c and e + e − →χ 0 nχ 0 n including soft and hard photon radiation. We mostly restricted ourselves to a version of our renormalization scheme which is valid for |M 1 | < |M 2 |, |μ| and M 2 = μ to simplify the analysis, even though we are able to switch to other parameter regions and correspondingly different renormalization schemes. The dependence of the chargino/neutralino cross sections on the relevant cMSSM parameters is analyzed numerically. We find sizable contributions to many production cross sections. They amount to roughly ±15% of the tree-level results but can go up to ±40% or higher in extreme cases. Also the complex phase dependence of the one-loop corrections was found non-negligible. The full one-loop contributions are thus crucial for physics analyses at a future linear e + e − collider such as the ILC or CLIC.

“…The charged Higgs pair in lepton colliders were studied extensively before in Refs. [15,16]. Since the production rate in e + e − -collisions is s-channel suppressed, the cross-section of γγ → H + H − is larger than that of e + e − -collider.…”

In this study, the charged Higgs pair production is calculated in the context of the supersymmetry at a γγ-collider. The channel is explored in Two-parameter Non-Universal Higgs Model where the model provides relatively light neutral and charged Higgs bosons. The computation is extended to one loop-level, and the divergence arising in the loop-diagrams are cured with the radiative photon correction. The production rate of the charged Higgs pair reaches up toσ LO+NLO UU = 121 fb at √ŝ = 635 GeV. The analysis of the cross-section is also given varying the parameters mA and tan β. The total convoluted cross-section with the photon luminosity in an e + e − machine is calculated as a function of the center-of-mass energy up to 1 TeV, and it gets up to 42 fb at √ s = 900 GeV depending on the polarization of the initial electron and laser photon.
