TL;DR

This paper proposes a model where leptons, quarks, and gauge bosons are composite particles made of six fundamental preons, explaining standard model features and suggesting a dark matter candidate.

Contribution

It introduces a Hexad Preon model with six preons transforming under a specific gauge theory, reproducing standard model particles and interactions from preon compositeness.

Findings

Reproduces three generations of quarks and leptons

Derives standard model interactions from preon dynamics

Suggests a dark matter candidate within the model

Abstract

A Hexad Preon model where leptons, quarks and W Z bosons are composite is proposed. Six Hexad Preons transform under $U(3)\otimes U(3)$ local gauge theory which is identified with $U(1)_Q\otimes SU(3)_C\otimes SU(3)_f\otimes U(1)_w$. All salient features of the standard model can be obtained from the compositeness of leptons and quarks: There are exactly six quarks and six leptons with evident three families (generations); All quantum numbers of leptons and quarks can be given out of that of preons; QED and QCD are given by electro-strong interaction $U(1)_Q\otimes SU(3)_C$ ; The weak interaction is residual "Van der Waals" forces between preons and dipreons. It is shown that all processes in standard model are just reshuffle of preons. In addition, a possible dark matter candidate is presented. Other questions like the electroweak symmetry breaking, the spin of fermions, the origin of quark and lepton mixing, \textit{etc.}, are also addressed.
