Abstract
We compute the next-to-leading order corrections to the gaugino masses M-i in gauge-mediated models for generic values of the messenger masses M and discuss the predictions of unified messenger models. If M < 100 TeV there can be corrections of up to 10% to the leading order relations M-i proportional to alpha(i). If the messengers are heavier there are only correctionas of a few %, We also study the messenger corrections to gauge coupling unification: as a result of cancellations dictated by supersymmetry, the predicted value of the strong coupling constant is typically only negligibly increased.
