Towards a Grand Unified Theory of Four Generations

  • Pei-you Xue

Abstract

We know that there are four fundamental interactions in nature: (a) Gravity; (b) Weak; (c) Electromagnetic; and (d) Strong (where QCD applies). The Glashow-Salam-Weinberg SU(2) × U(1) model is a unified theory of electro-weak interactions, i.e., (b) and (c) together. A Grand Unified Theory (GUT) attempts to unify (b), (c) and (d). The success of the GSW model and the progress of QCD leads people to expect that strong and electro-weak interactions will ultimately be unified. Various grand unified models have been proposed among which SU(5) and SO(10) are the most elegant. There are two problems still unresolved: the unification of generations and the gauge heirarchy problem. In this article we will present some attempts to solve the second problem.
