Fermion masses in grand unified theories: Effective Yukawa terms

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

It is argued that effective non-renormalizable terms of the type recently proposed by Ellis and Gaillard can give rise to large contributions to the fermion masses. The combined effect of this kind of term and the usual Yukawa couplings could explain the observed hierarchy of fermion masses. Two toy-models based on the gauge groups SU (5)×SU(2) H and SO(10)×SU(2) H (where SU(2) H is a gauged “horizontal” symmetry) are shown in which one can obtain some interesting mass relations previously obtained under very different assumptions.
