ANSATZ FOR QUARK, CHARGED LEPTON, AND NEUTRINO MASSES IN SUSY GUT(S)

We extend a fermion mass matrix ansatz by Giudice to include neutrino masses. The previous predictions are maintained. With two additional p arameters, a large Majorana neutrino mass and a hierarchy factor, we h ave seven further low energy predictions: the masses of the neutrinos, the mixing angles and the phase in the leptonic sector. We choose a r easonable hierarchy of Majorana masses and fit the overall mass scale according to a solution of the solar neutrino problem via the MSW mech anism, which is in agreement with the Cl-37, Kamiokande, SAGE and GALL EX data. We then also obtain a cosmologically interesting tau-neutrino mass.
