Type III Seesaw and Dark Matter in a Supersymmetric Left-Right Model

TL;DR

This paper introduces a supersymmetric left-right model that naturally achieves spontaneous parity violation, generates neutrino masses via type III seesaw, and explores implications for neutrino physics and dark matter.

Contribution

It presents a novel supersymmetric left-right framework with unique Higgs content and sterile neutrinos, enabling natural parity violation and neutrino mass generation through type III seesaw.

Findings

Spontaneous parity violation occurs naturally in the model.

Neutrino masses are generated via type III seesaw mechanism.

The model has implications for dark matter phenomenology.

Abstract

We propose a new supersymmetric left right model with Higgs doublets carrying odd B-L charge, higgs bidoublet and heavy Higgs triplets with zero B-L charge and a set of sterile neutrinos which are singlet under the gauge group. We show that spontaneous parity violation can be achieved naturally in this model and the neutrino masses arise from the so called type III seesaw mechanism. We also discuss the possible phenomenology in the context of neutrino masses and dark matter.
