What the Right Handed Neutrino Really is?

TL;DR

This paper explores the fundamental nature of the right-handed neutrino within the Standard Model, linking charge quantization, baryon and lepton number origins, and Wigner's Poincare group analysis.

Contribution

It provides a novel interpretation of the right-handed neutrino as a fundamental entity consistent with charge quantization and group theoretical principles.

Findings

Right-handed neutrino's nature is clarified through charge and symmetry considerations.

Baryon and lepton numbers arise naturally from the model.

The approach aligns with Wigner's irreducible representations of the Poincare group.

Abstract

We look into the concept of electric charge quantization in the Standard Model. The role of the vector nature of electromagnetism and that of mass generation by Yukawa coupling is studied. We show how the baryon and the lepton numbers arise naturally in this picture. This points to an unambiguous and fundamental understanding of the actual nature of the right-handed neutrino. This conforms to Wigner's analysis of the irreducible representations of the Poincare group.
