Masses of Quarks and Leptons and Mixing Angles in Anti-GUT Theory

Abstract

We describe a fit to the charged fermion mass hierarchy using the chiral quantum numbers of the maximal anti-grand unification group $SM{G}^3\times U(1{)}_f$, where $SMG\equiv SU(3)\times SU(2)\times U(1)$. This fit suggests a set of Higgs fields responsible for the breakdown, near the Planck scale, of $SM{G}^3\times U(1{)}_f$ to the Standard Model group.
