Preon Models in Particle Physics
Abstract
We summarize the standard model and grand unified theories in light of group theoretical properties. We discuss selected classic and modern preon models. Finally, a schematic preon model for all three generations of fundamental fermions in the standard model is constructed. This preon model introduces three spin 0 preons which represent the three generations, as well as two spin 1/2 preons. It incorporates handedness through the fermionic preons.
