What the Right Handed Neutrino Really is?

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.
