Abstract

We calculate the two-loop renormalization group equations for the running gaugino masses in general supersymmetry (SUSY) gauge models, improving our previous result. We also study its consequences on the unification of the gaugino masses in the SUSY SU(5) model. The two-loop correction to the one-loop relation m_i(\ensuremathμ)\ensuremath∝\mathrm\ensuremathα_i(\ensuremathμ) is found to be of the order of a few percent.
