Light Fermion Mass Hierarchies in Supersymmetric Models

摘要

We discuss radiative fermion mass hierarchies in grand unified supersymmetric models. There are arguments in the literature that these cannot arise. It is shown that these arguments only apply to a certain type of radiative hierarchy. Another type of radiative hierarchy can arise in simple SUSY-GUTs. We discuss examples. 15 references, 5 figures.
