Abstract

We present the full one-loop radiative corrections to pair production of neutralinos in e+e- collisions within the Minimal Supersymmetric Standard Model. Particular attention is paid to the definition of weak and QED corrections. The non-universal QED corrections are extracted by subtracting the initial state radiation. We give numerical results for two different SUSY scenarios for e+e- -> neu_1 neu_2 and e+e- -> neu_2 neu_2. The weak and QED corrections are up to several percent or even higher and need to be taken into account at future linear collider experiments.
