Flavour Mixing and Fermion Mass Generation as a Result of Symmetry Breaking

Abstract

It is shown that a simple breaking of the subnuclear democracy leads to a successful description of the mixing between the second and third family. In the lepton channel the ${\nu }_{\mu }-{\nu }_{\tau }$ oscillations are expected to be described by a mixing angle of $2.65^{\circ }$ which might be observed soon in neutrino experiments.
