Abstract

Inspired by the standard model of particle physics, we discuss a mechanism for constructing chiral, anomaly-free gauge theories. The gauge symmetries and particle content of such theories are identified using subgroups and complex representations of simple anomaly-free Lie groups, such as SO(10) or E6. We explore, using mostly SO(10) and the 16 representation, several of these "imperfect copies" of the standard model, including U(1)N theories, SU(5) - U(1) theories, SU(4) - U(1)2 theories with 4-plets and 6-plets, and chiral SU(3) - SU(2) - U(1). A few general properties of such theories are discussed, as is how they might shed light on nonzero neutrino masses, the dark matter puzzle, and other phenomenologically relevant questions.
