  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- -> cha_c cha_c' and e+e- -> neu_n neu_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|, |mu| and M_2 != mu 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 roughly 10-20% 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.
