Neutrino Masses, Leptogenesis, and Unification in the Absence of Low Energy Supersymmetry

TL;DR

This paper presents a model that explains neutrino masses, baryon asymmetry, and unification without low-energy supersymmetry, by integrating out heavy triplet fermions and avoiding proton decay.

Contribution

It introduces a novel non-supersymmetric framework that accounts for neutrino masses, baryogenesis, and gauge unification simultaneously.

Findings

Neutrino mass matrix consistent with observations

Successful baryon asymmetry generation

Unification achieved without proton decay risks

Abstract

We explore generating the dimension five operator leading to neutrino masses by integrating out heavy SU(2)_L triplet fermions. We exhibit a model that has a neutrino mass matrix consistent with observations. In addition, the model is capable of producing the observed baryon asymmetry, and unification can be achieved without dangerous proton decay. Supersymmetry can be broken at the fundamental scale with no supersymmetric signal at low energies.
