Two-loop SUSY QCD corrections to the chargino masses in the MSSM

The European Physical Journal C Aims and scope Submit manuscript

Abstract

We have calculated the two-loop strong interaction corrections to the chargino pole masses in the \(\overline{{\text{DR}^{\prime}}}\) 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 \(\mathcal{O}(\alpha\alpha_{\text{S}})\).
