See-saw Mechanism and Possible Generation Structure

TL;DR

This paper explores a new generation structure based on the see-saw mechanism, proposing a different lepton-quark combination and predicting a novel proton decay mode, assuming right-handed neutrinos are below GUT scale.

Contribution

It introduces a new scheme of particle generations that differs from the standard model, based on the see-saw mechanism and right-handed neutrinos.

Findings

Proposes a new generation scheme with different lepton-quark combinations.

Predicts a new proton decay mode.

Assumes right-handed neutrinos are below GUT scale.

Abstract

On the basis of see-saw mechanism, possible generation structure is investigated. Assuming that right-handed neutrinos are realistic particles below GUTs mass, it is shown that there is a choice of new scheme of generation,where the combination of leptons and quarks is different from the ordinary one. Our scheme predict a new proton decay mode.
