Underlying gauge-fermion models of compositeness

Abstract

We review recent advances in the construction of models of compositeness using four-dimensional gauge theories with fermionic matter. We discuss the group theory data needed to fulfill the basic phenomenological requirements and we touch upon the main predictions of these constructions.

Review of fundamental composite dynamics

“…Another important class of composite models [3] do not venture into extra dimensions but use fourdimensional gauge theories with specific group-theoretic constructions of the fermionic sector. The construction and predictions of such models are described in detail in this essay.…”
