Fermion Mass Hierarchy from Symmetry Breaking at the TeV Scale
arXiv:1011.5256
Abstract
In this paper we explore models in which we add a singlet scalar Higgs to the Standard Model. All of these models explain the origin of the mass hierarchy amongst the fermion masses and mixing angles. We discuss 24 different variations on this model, and explore the different phenomenological possibilities. We find that the phenomenological implications of all the models are very similar except in the Higgs sector. Higgs decays and signals can be altered very significantly in all the models, but break up into two distinct classes. We also describe a systematic method for generating these models from higher order interactions involving vector-like quarks and flavon scalars.
