Fermion Masses in Mininmal Supersymmetric SU(5) — •David Costa and Sören Wiesenfeldt — DESY Theory Group, Nokeststr. 85, 22607 Hamburg

We reanalyze the fermion masses in the context of the minimal supersymmetric SU(5) GUT Model, pointing out the mismatch between the unification of the charged lepton and the down-type quark Yukawa matrices. The addition of non-renormalizable terms lead to the correct mass relations. Finally, we consider the impact of the right handed neutrinos.
