An R-parity conserving radiative neutrino mass model without right-handed neutrinos

TL;DR

This paper explores a supersymmetric extension of the Zee-Babu radiative neutrino mass model that conserves R-parity, allowing for a dark matter candidate and consistent neutrino mass generation with observable collider phenomenology.

Contribution

It introduces a supersymmetric version of the Zee-Babu model that maintains R-parity and addresses neutrino masses, dark matter, and collider phenomenology.

Findings

Neutrino data can be fitted within the model.

The model remains consistent with lepton flavor violation constraints.

Potential signatures at the Large Hadron Collider are discussed.

Abstract

The model proposed by A. Zee (1986) and K.S. Babu (1988) is a simple radiative seesaw model, in which tiny neutrino masses are generated at the two-loop level. We investigate a supersymmetric extension of the Zee-Babu model under R-parity conservation. The lightest superpartner particle can then be a dark matter candidate. We find that the neutrino data can be reproduced with satisfying current data from lepton flavour violation even in the scenario where not all the superpartner particles are heavy. Phenomenology at the Large Hadron Collider is also discussed.
