摘要：
We have calculated the two-loop strong interaction corrections to the chargino pole masses in the (DR') over bar scheme in the minimal supersymmetric standard model with complex parameters. We have performed a detailed numerical analysis for a particular point in the parameter space and found corrections of a few tenths of a percent. We provide a computer program that calculates chargino and neutralino masses with complex parameters up to O(alpha alpha(S)).
