The standard model and the constituents of leptons and quarks

TL;DR

This paper formulates and confirms the standard model's postulates, deriving its Lagrangian, and explains how leptons and quarks are composed of elementary massless fermions exchanging scalar doublets, with charge quantization arising from SU(3) symmetry.

Contribution

It provides a complete set of postulates for the standard model and derives its Lagrangian, offering a detailed explanation of fermion composition and charge quantization.

Findings

Massive fermions are composed of elementary massless fermions exchanging scalar doublets.

Leptons belong to an approximate SU(3) octet, leading to charge quantization.

The Lagrangian for the standard model is derived from the postulates.

Abstract

A complete set of postulates of the standard model of the electroweak interaction and mass generation is formulated and confirmed deriving the Lagrangian for the standard model. A massive fermion is formed by a right-handed and a left-handed elementary massless fermion, exchanging a scalar doublet. The elementary massless fermions forming leptons belong to an approximate SU(3) octet. The charges are quantised due to this symmetry.
