Two-loop SUSY QCD corrections to the neutralino masses in the MSSM
arXiv:hep-ph/0612276 · doi:10.1016/j.physletb.2007.03.045
Abstract
We have calculated the two-loop strong interaction corrections to the neutralino pole masses in the DRbar'-scheme in the Minimal Supersymmetric Standard Model (MSSM). 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 agree with previously derived analytic formulae for two-loop corrections to fermion masses.
