Models of Lepton and Quark Masses
arXiv:2001.06582 · doi:10.1103/PhysRevD.101.035020
Abstract
A class of models is considered in which the masses only of the third generation of quarks and leptons arise in the tree approximation, while masses for the second and first generations are produced respectively by one-loop and two-loop radiative corrections. So far, for various reasons, these models are not realistic.
