Description
We consider the relations between the gauge couplings at the electroweak scale
and the high scale where unification of the three gauge couplings is expected.
Threshold corrections are incorporated both at the supersymmetric and at the grand
unified scale and, where available three-loop running and two-loop decoupling are
employed. We study the impact of the current experimental uncertainties of the
coupling constants and the supersymmetric mass spectrum on the prediction of the
super-heavy masses within the so-called minimal supersymmetric SU(5) and also of the
missing doublet model.
