How Neutrino and Charged Fermion Masses Are Connected Within Minimal Supersymmetric SO(10)

Massive neutrinos are a generic prediction of SO(10), and models of uni- cation cry for supersymmetry. Since we have a rather detailed information on neutrino and charged fermion masses, the real question is: how/whether it is possible to build a SO(10)supersymmetricmodel,thatcorrectlyincorporatesfermionmasses. Weshowthat asimple constructionis possible in the context of a minimal theory. We concentrate on the two heaviest generations, discuss the predictions of the model, and briefly comment on open questions.
