  For the search for electroweak (EW) particles 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, neutralino and
slepton production at e+e- colliders in the MSSM with complex parameters
(cMSSM). The evaluation is based on a full one-loop calculation of all possible
production channels including soft and hard photon radiation. The dependence of
the 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 many production channels 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.
