Supersymmetric Left-Right Model of Radiative Neutrino Mass with Multipartite Dark Matter

TL;DR

This paper presents a supersymmetric left-right model where neutrino masses are generated radiatively via dark matter particles, resulting in multiple stable dark matter candidates with distinct interactions, impacting experimental searches.

Contribution

It introduces a novel supersymmetric left-right framework where neutrino masses arise radiatively from dark matter, featuring multipartite dark matter stability and interactions.

Findings

Neutrino masses are generated radiatively from dark matter.

The model predicts at least three stable dark matter particles.

Potential observable effects on current and future experiments.

Abstract

The unifiable supersymmetric left-right model where the neutral fermion $n$ in the $SU(2)_R$ doublet $(n,e)_R$ is a dark-matter candidate, is shown to have the requisite particle content for the neutrino $\nu$ in the $SU(2)_L$ doublet $(\nu,e)_L$ to acquire a small radiative Majorana mass from dark matter, i.e. scotogenic from the Greek "scotos" meaning darkness. As a result, there are at least three coexisting stable dark-matter particles with different interactions. We study their possible phenomenological impact on present and future experiments.
