E6 GUT and Large Neutrino Mixing

Abstract

All experimental results concerning possible neutrino oscillations are naturally and simultaneously accounted for in an $E_6$ GUT model. The fermionic mass matrices are dictated by the symmetry breaking and specific radiative corrections and not by the use of ``Ansätze'' or discrete symmetries.
